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 a relative or sub-species of Thugly.

Physical Description
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 and becomes slightly larger. In his third and final stage, he turns from orange to red.

Attacks
Mugly only has four attacks. His most basic attack consists of running across the screen back and forth. During this time, his spikes are retracted, which makes him vulnerable to a jump attack. Mugly can also bounce along the stage, trying to crush Donkey and Diddy beneath him. The two simians can easily roll under Mugly and strike him on his vulnerable back. During Mugly's second and third stage, he can jump high in the air and create a huge shockwave when he lands. Also, during Mugly's second and third stage, he can charge fast at the duo, but this can be easily jumped over. This causes Mugly to run into a wall and succumb to dizziness. The Kongs then have a chance to jump on him while he is unconcious. During each stage, he attacks more often and performs them faster.
