Bats are enemies from the game Donkey Kong on the Game Boy. Bats make their first appearance in stage 4-5 in the Jungle. They fly horizontally across the screen. When they hit Mario, they hang onto him and appear to suck a little bit of blood out of him. Mario's face turns white (in the colored Super Game Boy version) and he falls off the rope he is currently climbing. After falling to the ground, Mario gets up again. Mario can also get killed by the bats if he falls too far after dropping from the rope.
