As Donkey Kong and Diddy Kong arrive at the end of the ruins, they come across a giant egg.
A Tiki drops the egg into a large cauldron and then moves in and possesses it. This boss, attached to the cauldron filled with bombs, is called Stu. Donkey Kong and Diddy Kong have their work cut out for them.
Stu flies around dropping bombs. The bombs will turn orange a few seconds before they explode, so you have a warning. Pick up the bombs and throw them at the bird to try and knock the Tiki out.
After dropping bombs, Stu will dive down to try and hit you. Duck down or hide between blocks for protection. Then pick up more bombs and keep throwing them at the bird.
Watch out for bombs that have a flame on them. You can throw them at Stu, but when they detonate on the ground, they send out a moving flame that travels across the ground and climbs right over the blocks. Jump over it to avoid losing a heart.
Stu also drops giant bombs. When you see one headed toward the ground, jump onto one of the golden blocks. When this bomb explodes, it sends out a shock wave that destroys the gray stone blocks and hurts you if it touches you.
Stu can also hurt you with the Tiki Booms. These will follow you around the arena for several seconds and then explode. Even if you jump over them, they will change direction and come after you. Just stay away from them while also avoiding Stu as it dives down on you.
As the fight continues, Stu will drop a row of bombs across the area and then dive down as you try to avoid them. When this happens, get in between a couple gold blocks and throw out any bombs here. That will keep you safe.
Keep picking up and throwing bombs at Stu. You need to get six hits to defeat this boss. Once you knock the Tiki out, run up and start hitting it to complete this level and advance to the next world.
