When Sid's attempt to adopt three dinosaur eggs gets him abducted by their real mother to an underground lost world, his friends attempt to rescue him.

Buck: Mammals, we have ourselves a crime scene. Tuff of fur. Half-eaten carcass. Hunk of... aaugh! No! Broccoli!
[almost throws up]
Buck: Here's what I think happened: dinosaur attacks Sid, Sid fights back with broccoli, leaving dinosaur... a vegetable!
Diego: Are you nuts? Sid's not violent. Or coordinated.
Manny: Yeah, and where's the dinosaur?
Buck: All right, good point. Theory two: Sid's eating broccoli, dinosaur eats Sid, dinosaur steps on broccoli, leaving broccoli... a vegetable!
Manny: Buck, when exactly did you loose your mind?
Buck: [thinks a moment] Three months ago. I woke up a morning married to a pineapple... An "ugly" pineapple.
[sighs lovingly]
Buck: But I loved her...
Crash: What's that sound?
Buck: It's the wind. It's speaking to us.
Eddie: What's it saying?
Buck: I don't know. I don't speak wind.
Diego: [to Manny, about possibly staying] This is my kind of place.
Buck: [Pick up a rock like it's a cellphone] Hello? No... No I can't really talk right now... Going to retrive a dead sloth. No, I know. They're following ME! Yeah, and they think I'M crazy! O-Okay... We're going into the Chasm of Death, I'm going to loose you. Yeah. O-Okay.
[quietly]
Buck: I... I love you too. Goodbye... Goodbye!
[throws the rock aside]
Buck: Let's get a move on, shall we?
Manny: [to Diego] That'll be YOU in three weeks.
Eddie: So, why did they come up with the "Chasm of Death"?
Buck: We tried "The Big Smelly Crack" but people kept giggling.
Sid: [about Peaches] Oh it's a boy!
Diego: That's it's tail
Sid: It's a girl!
Buck: [stopping Manny and the herd from moving on] Whoa whoa whoa whoa whoa! Whoa! What, you-you think this is some sort of tropical getaway? You can't protect your mate, mate. What are you gonna do with those-those flimsy tusks when you run into the Beast?
Crash: Wait. You mean there's something *bigger* than Mommy Dinosaur?
Buck: Aye.
Eddie: "Eye"?
Buck: Aye aye. He's the one that gave me *this*
[pointing to his missing eye, which is covered in a patch]
Eddie: Whoa. He gave you that patch?
Crash: For free? That's so cool.
Eddie: Yeah, maybe he'll give *us* one, too!
Buck: Hello Rudy!
Buck: Let me tell you about the time I used a sharpened clam shell to turn a T-Rex into a T-Rachel.
Manny: Sid, you're gonna have a family too someday. You're gonna meet a nice girl, with... with low standards, no real options, or sense of smell...
Buck: Rule no. 1: Always listen to Buck! Rule no. 2: stay in the middle of the trail; and rule no. 3:
[long pause]
Buck: he who has gas travels at the back of the pack
Manny: [Sid guards the three baby Tyrannosaurs from an adult] Sid! Give them to her! She's their mother!
Sid: How do I know she's their mother?
Manny: What do you want, a birth certificate? She's a *dinosaur*!
Ellie: [Manny and Diego are trapped by a meat-eating plant] That's it, I'm tearing that thing out through the root.
Buck: Do that, and it'll clamp shut forever.
Ellie: What?
Buck: Calm down, preggers. Don't get your trunk in a knot. I'll have them out of there before they're digested.
Manny: Digested?
Buck: They'll be nothing but bones in three minutes. Well, maybe five for the fat one.
Manny: I'm not fat!
Sid: [running from a musk ox he tried to milk] I thought you were a female!
Buck: The name's Buck. Short for Buckminster. Long for Buh.
Manny: Oh, we need a code word. Yeah, something that says, "the baby's coming."
Ellie: [thinks a moment] How about, "Aaah! The baby's coming!" How's that?
Manny: Nah, too long. We need something short and punchy, like, uh... "peaches"!
Ellie: Peaches?
Manny: I love peaches. They're sweet and round and fuzzy, just like you.
Ellie: You think I'm round?
Manny: Uh... Round is good. Round is foxy!
Buck: What are you doing here?
Ellie: Our friend was taken by a dinosaur.
Buck: Well, he's dead. Welcome to my world. Now, go home. Off you pop!
Sid: Fine, I understand. You have your family. I'll just go raise them alone... by myself. In my fortress of solitude. In the ice. A lone, lonely loner.
Manny: That's a lot of aloneness.
Sid: Precisely!
Manny: Ellie!
Ellie: [Hiding contraction from Manny] I'm fine! I'm just taking my time - --
[screams as rock formation begins to give way under her]
Manny: Ellie! Whoa!
Ellie: [Trying to balance] Manny!
Manny: Get to the ledge!
Sid: Is this how you resolve conflicts? No wonder you're single.
[Mamma Rex roars]
Sid: oh, that's your answer to everything. I don't exactly call that communication. I say they're vegetarian, you say "grrr". I say can we talk about it, you say "grrr". That's not what I call communication.
Mother T-Rex: GRRRRRR!
Sid: See that's your answer to everything!
Buck: [from trailer] Are you ready for adventure?
Crash, Eddie: Yes, sir!
Buck: For danger?
Crash, Eddie: Yes, sir!
Buck: For death?
Eddie: Uhh, can you repeat the question?
Ellie: [Has a sudden contraction] Oohh! Manny! Pineapples!
Manny: Pineapples?
Ellie: Mangoes? Pomegranates? Grapefruits!
Diego: She's ordering a fruit salad!
Ellie: Oh come on, think... think! Peaches!
Manny: Peaches?
[realizes the code]
Manny: Peaches! The baby's coming! What are we gonna do?
Sid: [to the baby dinosaur] Come on, spit him out. If you don't spit out little Johnny right now, we're leaving the playground this instant! One... two... don't make me say three...
[the baby dinosaur spits up a bird]
Sid: There you are. The picture of health.
Aardvark Mom: That's not little Johnny!
Sid: Well, it's better than nothing.
Buck: [Using dinosaur skulls like they're talking using his own voice]
[skull one]
Buck: They'll never survive. It's dangerous out there by day.
Buck: [skull two] And it's even worse at night.
Buck: [skull one] Plus, their guide is a lunatic.
Buck: [skull two] You mean Buck? He's wacko.
Buck: I am not!
Buck: [brings up another skull on his foot] And his feet smell.
Buck: Oh, shut up!
Buck: [skull on his foot] You shut up.
[Buck grabs his foot with the skull on it]
Manny: He's strangling his own foot.
Ellie: Maybe we should keep going.
Buck: [skull three] What? And give Rudy a midnight snack? Not likely.
Buck: The skull's right. Take a load off, Manny. We'll camp here for the night. Now, who's hungry?
Buck: [skull three] I am!
Buck: You don't need the calories.
Manny: [looking at Eddie & Crash singing] Are you crazy?
Diego: [lets go of his breath, in a squeaky voice] Its not poison!
[surprised by his voice, he laughs hysterically with Eddie & Crash]
Crash: [in a squeaky voice] That is Sooo Disturbing!
Buck: [from the other side] Stop laughing! All of you!
Crash: [in a squeaky voice, mimicking Bucks accent] Stop Laughing all of you!
[All laugh hysterically]
Manny: [in a squeaky voice, mimicking Bucks accent] Whats rule number 1?
[All laugh hysterically]
Ellie: They are just laughing, what's so bad about that?
Buck: They died laughing!
[points down the chasm at laughing skeletons of dinosaurs]
Ellie: [gasps] Stop laughing!
Manny: [in a squeaky voice] You know whats funny though? We are trying to save Sid, and now we are all gonna die!
[all laugh hysterically]
Eddie: [in a squeaky voice] And i don't even like Sid!
Crash: [in a squeaky voice] Who does? He's an idiot!
[All laugh hysterically]
Diego: [in a squeaky voice] Thats for getting me into this mess! Its the most fun i've had in years!
Manny: [in a squeaky voice] Thank YOU, for deserting the herd, that was totally SUPER!
[moment of silence and then they all laugh hysterically]
Manny: [All notice Buck above the cage trying to release it free and holding his breath, Manny begins to tickle him with his trunk] Coo chee Coo chee Coo!
Buck: [In a normal voice] Stop That!
[gasps]
Buck: Don't you see?
[in a squeaky voice]
Buck: We are all gonna die!
[All look at him and begin laughing hysterically including Buck]
Ellie: [on the other side] I gotta do everything huh?
[Ellie releases the rope and sets the cage loose]
Eddie: [in a squeaky voice] Sometimes, i wet my bed!
Crash: [in a squeaky voice] Thats alright, sometimes I wet your bed!
[All Laugh hysterically]
Manny: [the cage reaches the other side and everyone apart from Buck tumbles out breathing for air while laughing. In a normal voice] Uhhh, I'm not sure how much of that you could hear...?
Manny: Oh i heard all of it
Eddie: [to crash] You wet my bed?
Crash: That was just gas talk dude.
Buck: Grab that ammo!
Crash: [Using Eddie's tail as sling-shot] Bogey, three o'clock! Fire!
Eddie: This is awesome!
Crash: Light it up! Yeah!
Eddie: Hasta la vista, birdy!
Manny: Don't ever yabba-dabba-do that again!
Manny: Sid, whatever you're doing, it's a bad idea.
Sid: Shh! My kids will hear you.
Manny: They're not your kids, Sid. Take them back. You're not meant to be a parent.
Sid: Why not?
Manny: First sign: stealing someone else's eggs. Second sign: one of them almost became an omelet.
Ellie: [a Tyrannosaurus has come forward] I thought those guys were extinct.
Manny: Well then, that is one *angry* fossil.
Manny: Don't move a muscle.
Molehog: [running] AAAAAAAH!
Crash: Have you ever flown one of these before?
Buck: No. First time, actually.
Buck: There's only one thing to do. Possums, come with me. Manny, you stay and take care of her.
Manny: You can't leave now! She's off the trail! What about rule number two?
Buck: Rule number 5 says you can ignore rule number 2 if there's a female involved, or possibly a cute dog. You know, I just make up these rules as I go along.
Manny: I feel so... puny.
Sid: [confronting a Tyrannosaurus who has come looking for her babies] Look, these are my kids! And you're gonna have to go through *me* to get them!
Manny: Bring it on you chicken-headed freaks!
Sid: [after being rescued by flying dinosaur] Help!
Eddie: [Looks over side of dinosaur] No, Sid, it's me!
Crash: [Looks over also] And me!
Buck: [Joins Crash & Eddie] And me!
Sid: Uh, I don't wanna panic anyone, but who's flying this thing?
Buck: Oops!
[Crashes into ice ceiling]
Crash: You are super weasel!
Eddie: Ultra weasel!
Diego: Diesel weasel!
Buck: The Buck stops here!
Manny: After we rescue Sid, I'm going to kill him.
Buck: We're hit! We're hit! Mayday! Mayday! We're losing altitude!
[Taps flying dinosaurs eyeball]
Buck: Hold these!
[Hands reins over to Crash & Eddie, and begins mouth to mouth on dinosaur]
Buck: Oh, tastes like fish.
Eddie: Okay. That's just weird. I love you, bro!
Crash: I know!
Buck: Snap out of it! Come on!
[Punches dinosaurs nostril; dinosaur wakes up]
Sid: I'm a single mother with 3 kids. I could use a little compassion.
Manny: Well uh, We better get moving!
Diego: Aren't We forgetting something?
Buck: [Buck is sliding down the vine through the tocix fumes, in a squeaky voice] Here Rudy, Rudy, Rudy! HaHaHaHa Oh im so lonely!
Ellie: We've been living above an entire world, and we didn't even know it!
Sid: Well, I see someone else who has a bun in the oven!
Pudgy Beaver Mom: Oh! I'm not pregnant!
[Hits Sid with stick]
Sid: Ow! It's too bad. You'd make a wonderful mother.
[Gets hit again]
Sid: I'm too young to be eaten!
Ellie: [Grabs fern] Here, boy! Here! Come on! Good boy! Come on! Climb on.
Manny: Are you nuts? We're not getting on that thing!
Ellie: It's either this dinosaur or that one! Pregnant lady wants to live! Yabba-dabba-doo!
[Slides down dinosaur's back]
Buck: Now then, eyes forward, back straight... oh, and breathe in the toxic fumes and you'll probably die.
Ellie: Toxic fumes?
Buck: Just another day in paradise!
Ellie: Manny! Pineapples!
Buck: Pineapples?
Manny: She gets cravings.
Ellie: Pomegrantes? Grapefruits! Nectarines?
Diego: She's ordering a fruit cocktail.
Ellie: Come on, think! Peaches!
Manny: Peaches? Peaches! The baby! What, what now?
Diego: This? Not good.
Manny: [Freaking out] The baby's coming!
[to Crash and Eddie]
Manny: Did you guys hear that? Cause sometimes I imagine it in my head, but...
Crash: Can you try to hold it in?
Ellie: Can somebody slap him for me?
Eddie: [Slaps Crash] Done and done.
Manny: Just sit tight. We're coming!
Manny: Guys don't talk to guys about guy problems. They just... punch each other on the shoulder.
Ellie: That's stupid!
Manny: To a girl... To a guy that's like six months of therapy!
Diego: Whoo! My paws are burning, baby! They're burning! I gotta tip-toe. Tippy-toe. Tippy-toe.
Ellie: Excuse me, twinkle toes! Giving birth here.
Diego: Oh, right, sorry. You okay?
Ellie: Am I okay? Do you know anything about childbirth?
Diego: Not really. But Manny's coming.
Ellie: Diego, I'm scared. Can I hold your paw?
Diego: Yeah, of course.
[Groans as Ellie takes paw and squeezes hard]
Diego: Just go with the pain.
[Ellie screams]
Diego: It's just a contraction.
Ellie: No!
[Points to dinosaur and screams]
Diego: Don't worry about a thing. You're doing fine.
[Sees dinosaur]
Diego: It's going great. Excuse me.
[Bonks dinosaur on head, dinosaur grabs Diego's leg and pulls him over ledge]
Diego: Just keep breathing!
Ellie: Diego!
Diego: [Pops back up holding two dinosaurs] Just breathe! That's the important thing.
[Conks dinosaurs' heads together, and jumped by another]
Diego: Oh!
Ellie: You can do it! Push! Push!
[Diego pants and lays on back as though giving birth]
Diego: I can't do it!
Ellie: Just one more big push!
Diego: You have no idea what I'm going through!
[Ellie looks at him]
Diego: Okay, forget I said that. Let's do this together.
[Pushes log holding back two dinosaurs over ledge]
Diego: [Coaching Ellie in breathing] Oh, getting dizzy. Manny!
[Helps Manny up]
Diego: Come on, buddy I think we're getting close.
[Baby cries]
Sid: Bad egg! Rotten egg! A heart attack you almost gave me!
Manny: Guys don't talk to guys about guy problems. They just... punch each other on the shoulder.
Ellie: That's stupid!
Manny: To a girl. To a guy that's like six months therapy! Fine.
[walks over to Diego, punches him in shoulder]
Diego: Ouch. What was that for?
Manny: [pause] I don't know.
Eddie, Crash: [after inhaling the poison gas] Let's do it!
[singing]
Eddie, Crash: Christmas, Christmas, time is here!
Sid: [Climbs in log and sighs believing he's lost Rudy. Rudy steps on both side of log leaving Sid in the middle] Go away! Go away! Shoo! Stranger danger! Stranger danger!
Sid: [after Diego leaves, looks in ice at his reflection] At least you've still got your looks.
[ice cracks]
Crash: Dude, You're awesome! You're like the brother I never had!
Eddie: Me too!
Ellie: Talk to the trunk.
Diego: [trapped in man-eating plant with Manny] I feel... tingly.
Manny: Don't say that when you're pressed up against me!
Diego: Not that kind of tingly!
Manny: I can feel it too!
Manny: [Buck looking very spaced out by Crash and Eddie's lack of understanding his eye prospect turns to Manny who said in a slight sarcastic voice] Welcome to my world!
Buck: It smells like a buzzard's butt fell off and was sprayed on by skunks.
Diego: That's Sid.
Crash: This place is totaled.
Eddie: And we didn't wreck it.
Crash: We're losing our touch, bro.
Eddie: So, Why do they call it the Chasm of Death?
Buck: Well, We tried big smelly crack but uh, that just made everybody giggle!
Manny: Well now what?
Buck: [Buck pulls on a cord and a large ribcage on a vine appears] Madam...?
[gestures for Ellie to get on]
Manny: Whoa! She is not doing that!
Buck: Bup bup bup bup! Rule number 1...?
Eddie: Ooh ooh ooh!
[raises his hand in the air]
Buck: Ah! Come on mammoth! You're supposed to have a good memory!
Ellie: Always listen to Buck!
[walks onto the rib cage]
Buck: Now eyes forward, Back straight and
[quietly]
Buck: breath in the toxic fumes and you'll probably die.
Ellie: TOXIC FUMES?
Buck: Just another day in paradise!
[cuts the vine to release the rib cage]
Manny: Wait!
Buck: GERONIMOOOOOOOOOOOOOOOO!
Manny: [moment of silence and then sees the empty ribcage move towards them] Ellie? You okay?
Ellie: [calling from the other side] You have to try this!
Buck: Alright! Now Pile on everyone! Couldn't be easier!
Buck: [the cage is stranded in the middle of the fumes] Don't panic! Just some uh technical Difficulties! Keep holding it in boys!
Eddie: [Stops holding his breath] I cant take it anymore!
Crash: He breathed it!
[gasps]
Crash: now I'm breathing it!
[crash & eddie make choking noises]
Eddie: [in a squeaky voice] Hey! We're not dead!
Crash: [in a squeaky voice] You sound ridiculous!
Eddie: [in a squeaky voice] Me? You should hear you!
[Both laugh hard]
Eddie: [in a squeaky voice] Alright Alright. and a one, and a two...
Crash, Eddie: [in a squeaky voice, singing] Christmas, Christmas time is near...
Diego: [to Manny] For the record, I blame you for this!
Sid: I know what it's like to feel abandoned.
Ellie: This is the world our baby's gonna grow up in, you can't change that.
Buck: Pop goes the weasel!
Diego: Look, who are we kidding, Manny, I'm-I'm-I'm not a kitty-cat, I'm a sabre. I'm not really built for chaperoning play-dates.
Ellie: That's right sweetheart, welcome to the Ice Age!
Buck: We're not alone, are we?
[Rudy appears and roars]
Buck: Hello, Rudy.
Gazelle: Eat my dust, dingo!
Ellie: [Talking about Sid being missing] This isn't your fault. It's bigger than both of us. We have to get Sid
Manny: Yeah. But if I have been a better friend to him... we wouldn't be here.
Buck: [interrupts] Better friend, Are you pluckin' my whiskers? You risked your life, your mate and your baby to save your buddy! Not the best husband or father... but a darn good friend!
Sid: The important thing is nobody got hurt... except for that guy... and-and those three...
[trips over someone]
Sid: ... and her.
Sid: [As, Sid fails to fight back against the boiling lava river and is doomed to certain death as he gets nearer to the lava falls, he stands up dignified on his floating rock, putting his hand to his chest] This... is the end of Sid the sloth...
[Falls over lava falls]
Sid: Aaggghhhhh!
Crash: Dude, you're awesome! You're like the brother I never had!
Eddie: Me too!
Buck: [Buck sees a large butterfly as it takes off] I knew that guy when he was a caterpillar, you know, before he came out.
Diego: [laughing under the effects of the toxic fumes in the Chasm of Death] Thanks for getting me into this mess. It's the most fun I've had in years.
Manny: Thank *you* for deserting the herd. That was totally super!
[Both break out laughing]
Buck: [after Manny and Diego get trapped in giant plant] It's time to get... Buckwild!
