He’s a cat who’s a ninja, he wears a ninja suit, he has a ninjato, he has triangular legs and a round body, with a ninja suit

Normal cat, he’s the basic standard cat, he has triangular legs with a round body

Tank cat, he’s tall, and tanky, cant damage anything though, he’s weak, he has triangle legs with a long body, not a literal tank (for the bot to understand)

He’s a knight, he’s in heavy armor, which is why he is slow, he’s carries a big lance, he has triangular legs with a circular body but he has knight armor

A cat that dresses like a cartoon caveman, he uses a big bone as a weapon, the same as the other cats but with a caveman pelt, he looks the youngest

He carries a sword and shield, and he has a headband with a purple crystal (I assume) on it
