A young boy is recruited by his imaginary friends Sharkboy and Lavagirl to help save their planet.

Lavagirl: Thanks for saving me, Sharkboy.
[Lavagirl kisses Sharkboy on the cheek and he sizzles]
Sharkboy: [smiling a little painfully] Ouch.
[train of thought is out of control]
Lavagirl: [panicky] What do we do?
Sharkboy: [calmly] Yell? Scream?
Lavagirl, Sharkboy, Max: [screaming]
Mr. Electricidad: OK, kids, who's next? Remember, there are no dumb ideas.
Linus: Maybe we can freeze his circuits!
Mr. Electricidad: That's the dumbest idea I've ever heard. We're in the middle of Texas in August!
[Max had just imagined a banana split boat in the Land of Milk and Cookies]
Sharkboy: You still hungry, Max? How about a knuckle sandwich?
Sharkboy: Usually, if you snooze, you lose. With Max, you snooze, you win.
Sharkboy: [singing] Close your eyes, shut your mouth, dream a dream and get us out. / Dream, dream, dream, dream, dream, dream. / Hit the hay, fast asleep, dream a dream, you little blip. / Dream, dream, dream, dream, dream, dream.
Lavagirl: It's working! Keep it up, Sharkboy.
Sharkboy: [singing] Just relax, lay about, or my fist will put you out. / Dream, dream, dream, dream, dream, dream. / Take your time, but beware, there's darkness in the air. / Dream, dream, dream, dream, dream, dream.
Lavagirl: Dream about me next, Max. I need to know who I am. Not just destruction or a simple flame. Dream of me as something good.
Sharkboy: [singing] Don't despair, step right up. Glass of water? Here's a cup. / Dream, dream, dream, dream, dream, dream.
Lavagirl: He's having a nightmare! Wake up, Max! Wake up! Stop that racket Sharkboy - you're giving him nightmares!
Mr. Electric: 'Watt's' up?
[last lines]
Max: So dream a better dream; then work to make it real.
Tobor: Yes?
Lavagirl: Hot lava... Hot lava...
[Lavagirl starts melting, turning into lava]
Max: He ruined my Dream Journal!
Linus: I did not! Mr. Electric, send him to the principal's office and HAVE HIM EXPELLED!
Sharkboy: [while singing a lullaby to Max] Close your eyes / Shut your mouth / Dream a dream / And Get us out / Dream, Dream, Dream, Dream, Dream, Dream / Hit the hay / Fast asleep / Dream a dream / You little bleep / Dream, Dream, Dream, Dream, Dream, Dream...
[Lavagirl smiles at his dancing and singing]
Sharkboy: [cracks knuckles] Get ready for the ultimate power outage.
Mr. Electric: [flexing muscles] And who are you to believe that you can defeat me now?
Sharkboy: No one special. Just... king of the ocean.
[Sharks cut ice that Mr. Electric is on, he falls in the water, and the sharks bite him]
Sharkboy: Shark frenzy.
[Sharkboy walks away]
Mr. Electricidad: [after Mr. Electric is destroyed] He's... unplugged!
Lavagirl: Everything that is or was began with a dream.
Mr. Electricidad: What I can't believe is you dreamt me as a big round bad guy! I'm not bad!
Lavagirl: Row row row your bananasplit-boat, gently down the steam of consciousness, merrily merrily merrily, live is Max's dream.
Lavagirl: When you dreamt up these giant cookies, who did you expect to be able to eat them?
Max: I really didn't think about it.
Lavagirl: 'Cause if you dream giant cookies, something has to be created to *consume* giant cookies.
[cookie giants appear from behind mountains]
Sharkboy: Cookie giants!
