In the first phase, Kleptyrant will be standing on a pillar with Cappy in a cage behind him. When you try to jump at him, he will leap towards another pillar with Cappy in his beak. There are 10 pillars with 5 pairs of 2 colors. You have to get him to fly over to a low pillar, and then reach the elevated pillar of that color without causing him to flee and ground pound, hitting him. After doing this three times, the second phase will start. A cutscene plays where Kleptyrant destroys all the pillars and then puts Cappy on his head. He then starts to fly around and numerous trapeetles crawl out of the ground. In this second phase, he will launch Cappy at the trapeetles in an attempt to hit you with them. You need to dodge them and get it so Cappy hits Kleptyrant instead. Do this three times to defeat him and get Cappy back.

Once in a while, he will launch the chain chomp at you, giving you a chance to capture it.
