They are fake pets, that have absolutely nothing to do with pokemon, it has DINOSAURS instead. I think they're like multi-pets. copy pasta time from tameangerie
Pokemon pet
Unofficial pet. Not licensed by Nintendo.
The character is not a Pokemon, it's a dinosaur.
I suspect the guts are of the Dinosaur V.s. Gorilla one like this:
It's has very nice animations and is a very imaginative pet.
One of the games is "whack-a-mole".
You can also have him lift weights with his tail, run on a treadmill.
He battles with a gorilla. If he loses, he goes right to the hospital.
He also seems to really enjoy his hot bubbly showers.
Of course I was hoping this to be a Pokemon character, but even this dinosaur is very nice!
