K. Lumsy is a major character in DK64. He is a prisoner in a small island next to K. Rool's mechanical island. He is locked up in a cage by King K. Rool because he didn't want to harm DK Isles, especially the Kong family. DK and his friends free him by defeating the bosses of the 7 levels, and find a hidden key in Hideout Helm. When all the locks are removed, K. Lumsy is set free and frolics around DK Isles and knocks down the flying croc. Then he takes the Kongs for a swim at the very end.
