Squeekly

Squeeklies are purple, bat creatures that inhabit in Donkey Kong Island and first appear in the game Donkey Kong Country Returns. Squeeklies are semi-common enemies that appear in some levels of the Cave and the Forest. For Donkey Kong and Diddy, these baddies are more of an obstacle than an enemy, as all they do is fly straight forward. The Kongs can defeat a Squeekly by jumping on it or throwing an object like a barrel at it.

They make a prominent appearance in the Crowded Cavern level of the Cave. The level features the Squeekly Family, a big group of bats of various sizes that show many types of attacks. The family has some small Squeeklies that attack in the front, medium size Bobbin' Squeeklies that attack by flying up or down when they feel their victims coming, and a large Mega Squeekly that chases the Kongs throughout the level, able to emit powerful sonic waves from its mouth to hurt the primates. Unlike the Squeeklies that appear in other levels, these Squeeklies cannot be defeated in any way, although the large Squeekly shows problems avoiding large walls during the chase and eventually is knocked down by one at the end of the level.
