Kōmori

Kōmori are bat enemies that appear in Mario vs. Donkey Kong. They fly in a straight horizontal line across the screen from a small roost, making a minor descent and changing direction whenever they pass one of the level's margins, usually traveling past ropes.

Whenever Kōmori fly into Mario, they hang onto and throttle him, causing Mario to fall off the rope he is currently climbing. Mario can either survive crashing onto the ground or lose a life, depending on the height reached where the bat enemies intercepted him.
