Chomper keeps offering him them sometimes. What if, perhaps as a joke, Littlefoot actually DID eat one? Apart from freaking out the Great Valley residents, what do you think Littlefoot would do:
Littlefoot: PTTTTTTTTTTTTTTUUUHHHHHH! (What Sharpteeth do when they eat green food)
Littlefoot: Look, I'm a Bothtooth!
Littlefoot: Poor poor crawler. Why did I do that?
I've seen Chomper eat green food. I'm just curious what would happen if one of the Gang of Seven (minus Chomper and Ruby) ate meat, even if by accident.
It would be fun to see, wouldn't it? I mean, it's gotta be possible that maybe Spike at least would eat a crawler on a tree star and not take the time to notice. (Spike almost ate Ducky at least once. Don't you think he couldn't accidentally eat a crawler or something?)
