Mugly

Mugly is a boss appearing in the game Donkey Kong Country Returns and Donkey Kong Country Returns 3D. He is the first boss that Donkey Kong and Diddy Kong face. Mugly is faced in the Jungle area and his mission is titled Mugly's Mound, where he is hypnotized by Kalimba Tiki. He is presumably related to Thugly, the boss faced at the end of the Cliff area.

At first, Mugly is a yellow dinosaur-like monster. He walks on all fours and has a huge mouth with many white, sharp teeth. Mugly has two lazy eyes as well. The monster is covered with red spikes that he can retract at will. During Mugly's second stage, he becomes orange instead of yellow. In his third and final stage, he turns from orange to red.
