This is when Jesse realizes that Willy is going to dry up if he, Littlefoot, Ash, Cartman, Randolph, and the others don't get to the lake faster.
Jesse: (speaking) We gotta hurry! He's not doing so good!
Petrie: (singing) We all hurry now. No time to look back.
Chomper: Follow me.
Ducky: And do not let go of the whale. It'd be very, very bad if he dries.
Cartman: (singing in Nod's voice) Well, I'm not sure this idea's a good one.
Kyle: (singing in Mutt's voice) What if that Team Rocket there were to catch us?
Cartman: (singing in Nod's voice) Why don't we leave the whale right here and run?
Ducky: We are to close to home to leave him here. If he should fall, he might find a way back to the pool.
Chomper: We must be brave.
Petrie: And move this whale.
Chomper: Or are you scared?
Cartman: (in Nod's voice) Scared?
(Chomper stares at Cartman to make him tell the truth)
Cartman: (laughing in Nod's voice) I'm not scared. You scared, Kyle?
Kyle: (in Mutt's voice) Well, maybe-- (Cartman hits Kyle) I mean, no! I'm... not... scared.
Cartman: (in Nod's voice) Right! Then... let's move this whale.
Chomper: I hope Team Rocket doesn't block our way there.
