Animals? [Now Red is the one repeating words he's never heard about. He pauses, trying to think of another word.] They're called creatures sometimes... [That's the only other word used for them.] By teachers.

[It's an odd word to say, like it's too scientific. And when you already have a good enough word to use, why say anything else? But that could be what's going on here.]

Maybe you call pokémon animals where you're from? But pokémon are everywhere! There's even more pokémon than people I bet.
