Bats are enemies found in Croc (Game Boy Color).
Bats are one of the most common enemies in the entire game, appearing in nearly all of the homeworlds.
These gray bats fly up and down on the spot at the same speed, regardless of where Croc is.
Croc can tail-whip them or stomp them as he can most enemies in the game. Alternatively, he can just run underneath them whilst they're ascending.
