Mugly

Mugly is a lizard-like beast who acts as a boss in the Jungle area of Donkey Kong Country Returns. Like many of the other animals on Donkey Kong Island, Mugly is under the control of the Tiki Tak Tribe.

Battle
Donkey Kong and Diddy Kong encounter him in a colosseum eating many of Donkey Kong's bananas. Mugly is then hypnotized by the Kalimba Tiki and forced to attack Donkey Kong and Diddy Kong. It attacks by charging at them. The Kongs can jump over its attack and land on the target-like area on Mugly's back to cause damage. Over the course of the battle, Mugly will move faster, do high jumps, and become enraged. Mugly takes a total of nine hits. After the battle, Kalimba Tiki will emerge, dizzied, and the heroes can punch Kalimba out of the arena.

Trivia

 * Diddy can "feed" peanuts to the bosses Mugly or Thugly. If either of their mouths are open, they will catch them. After a certain amount of peanuts, they will stop to chew on the nuts, and expose their weak points, making them vulnerable to attack. This is indicated by hearts surrounding their heads, and only lasts for a short time. The player can only deal one hit, and then the boss will come back to their senses.
