Flapper

Flappers are bat enemies who appear in a few Kirby games. They first appear in Kirby's Dream Land. Flappers are like regular bats and fly around, sometimes after Kirby. They are usually encountered in dark areas.

In Kirby's Dream Land, a few Flappers are encountered in Castle Lololo.

In Kirby's Pinball Land, Flappers are sometimes released by Kracko during his boss fight.

In Kirby's Dream Course, a Flapper appears as an ally. During the night, if Kirby falls out of bounds, a Flapper appears carrying a trapeze for Kirby to grab on and return back on course.

Physical appearance
Flappers are a black bat with a small, round body and large wings. In their Kirby's Dream Land artwork, Flappers have completely yellow eyes, and cat-like ears with pink insides. In Kirby's Dream Course, their main body was changed to dark blue, their wings and insides of their ears to light blue, and their eyes were made entirely white. In Kirby: Right Back at Ya!, Flappers have a dark purple body, but their features are otherwise the same.
