Mugly

Mugly is a boss appearing in the game Donkey Kong Country Returns. 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 of Thugly.

Appearance
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.

Trivia
In 2 player co-op mode if Diddy Kong fires a peanut at Mugly or Thugly enough peanuts at the times they will retract their armor and eat the peanuts.
 * According to the Prima Official Guide, Mugly is related to Thugly.
