There are only two pets in the game for some reason.
- There is the Woody pet, who helps you collect resources, like wood and stone. I assume the amount of resources gained per hit hit increases with evolution stage. (But I wouldn't know, I only like C.A.R.L.
- The other pet is C.A.R.L., who assists the player in attacking a target. The amount of damage per hit increases with level and evolution stage.
i think C.A,R.L is the best also
