Krunk is the first boss in Crash Nitro Kart and is fought in Jungle Boogie. Before Krunk's race, he refuses to race until Velo informs him that they are from Earth, which angers Krunk because he thinks that Earth is a copy of his home planet, Terra. After Krunk's defeat, he says that Terra is free to roam since they have Terra's key. He then states that he is sorry for the words he had said about Earth and says that Terra is actually a copy of Earth instead of Earth copying Terra. Crash gives Krunk his yo-yo and makes friends with the bandicoots (until he is sent away by Velo).
