Mugly is a boss from Donkey Kong Country Returns. He is a yellow rhinoserous that has spikes on his back. In order to defeat Mugly, the player must jump on his back when his spikes are retracted. In Super Mario 3D World Mugly was going to appear as a boss in Donkey Kong's Jungle. Mario or Luigi must ground pound on his back. After three hits Donkey Kong slams down on his head a defeats Mugly which then the player will face Donkey Kong. He was considered a mini-boss in the game. He was taken out because Donkey Kong was very challenging and the player would have died at some point during either battle and due to no going back to get items for Donkey Kong's battle.
