Skittler

Skittlers are spider enemies first seen in Donkey Kong Country Returns. These enemies only make an appearance in the fifth world of the game, Forest, where they have the ability to differ colors by changing yellow to purple or purple to yellow.

Donkey Kong Country Returns/Donkey Kong Country Returns 3D
The yellow Skittlers try to attack Donkey Kong and Diddy Kong by swinging down from their webs to attack the Kongs. Donkey Kong and Diddy Kong can simply jump on the Skittler to defeat it. The purple ones, however, do not physically attack the Kongs, but they do swing around as an obstacle for the Kongs. If the spider is jumped on, it falls from its web and walks to the Kongs. The Kongs must then jump on the purple Skittler in order to defeat it.

Donkey Kong Country: Tropical Freeze
In Donkey Kong Country: Tropical Freeze, one Skittler got a cameo. It can be seen in the background of the level Forest Folly, frozen in a block of ice.
