Sid: Maybe we could rapidly evolve into water creatures.
Diego: That's genius Sid.
Sid: Call me "Squid"!

Sid: We're gonna live! *water rises up to his ankles* We're gonna die!

Sid: Manny, who do you like better, me or Diego?
Manfred: Diego. No contest.
Ellie: Manny, you can't pick favorites with your kids!
Manfred: He's not my kid. He's not even my dog. If my dog had a kid, and that kid had a pet, that would be Sid.
Sid: Manny, can I have a dog?
Manfred: No
Sid: Ellie, can I have a dog?
Ellie: Sure, sweetie.
Manfred: Ellie, we have to be consistent with them!

Diego: That ice is lookin' pretty thin.
Sid: Sure it's thin. But it's strong enough to hold a 10 tonne mammoth and a 9 tonne possum.

Manfred: I don't think her tree goes all the way to the top branch.
