Rick is the warmest out of the three, due to being a mammal

Coo's feathers are very fluffy

Kine's scales are quite smooth, and he's a pretty good swimmer (well he is a fish)

They have nomadic tendencies, but do often chill at Rick's nest when they want to stay in a single place

Rick's nest is actually quite close to Kirby's house

They enjoy hanging out with Kirby, Bandee, and Gooey

ChuChu and Pitch are Coo's honorary kids

Nago and Rick have been friends since childhood, and can be seen hanging out often

All six of them will attack you if they see you harming nature

Rick is an honorary member of the squeaks
