We came to this planet for some peace and quiet,
No more mercenaries, villains, or nefarious space-pirates,
What's that?! Over there?! In the fields!
It's a beast! Really tall! Sharp teeth! Long claws!
Turns out, somehow, the beasts could be controlled,
Caboose taught the dinosaurs how to rock and roll
CABOOSE DRUM SOLO!
- Carolina, Grif, Tucker, and Caboose's band was first shown in Previously On before their song was played during the end credits Epilogues.
