Stu is the third boss in the game Donkey Kong Country Returns and Donkey Kong Country Returns 3D. He is the boss of the Ruins area, appearing in the level Ruined Roost. Stu is just an egg before he is hypnotized by Gong Tiki. After being defeated by Donkey Kong and/or Diddy Kong, Stu's "armor" will further crack, causing him to fall down, and then fall apart exposing his torso, resulting in Donkey Kong and Diddy Kong comically placing their hands on their eyes to avoid looking at his body, yet peeking anyways.
Stu is a giant red bird with blue and yellow-tipped feathers and blue talons. He has a big yellow beak, blue eyes, and purple eyelids. Stu wears a golden crown with a jewel in its center. He has a bare pink torso that is covered with a golden cauldron filled with bombs (although the presence of red, white, and blue feathers when it breaks would imply that the bare torso was not natural as much as his feathers dislodging from the forceful destruction of his golden cauldron).
Stu's most basic attack is throwing three bombs. These bombs usually take a while to explode. However, occasionally, Stu will throw a bomb that will explode rather quickly. At half health, Stu will throw a rocket bomb with a yellow skull face. This will blow up when collided, and create flames that move through the whole arena. After Stu is hit once, he is able to swoop down. The only way to avoid this is to duck or be between two pillars. After Stu is hit three times, he will throw a huge missile in the middle of the arena, which will explode and cause an explosion to destroy the bottom part of the pillars. Donkey and Diddy Kong must either jump over the explosion, or stay on the gold part of the pillars. He will also throw multiple bombs. Most of these are already orange and will explode shortly. Occasionally, Stu will send some Tiki Pops to go after Donkey Kong and Diddy Kong. They will explode shortly after.
To defeat Stu, Donkey Kong and Diddy Kong will have to throw bombs at Stu. Once Stu is hit with bombs six times, he will be knocked unconscious and Donkey Kong can defeat the Tiki that possessed him.
