No more hind legs!!!!! no more animals

Here they come

"Four legs good, Two legs bad"

My rules:

• If it starts on 2 legs it should stay on two legs (like rowlet,scorbunny,squirtle etc) tho it is fine if it goes bipedal to quadruped (like samurott)

• If it starts on 4 it should stay on 4(like bulbasuar,mudkip,chikorita)but if it’s a quadruped and becomes bipedal than that’s no good

Birds are always two legs lol(they are superior)

It could happen

Have they before?
