Usagihebi, Cocox, and Lionbuta were there to witness Buggy's crash-landing on the Island of Rare Animals and the subsequent battle between him and Gaimon.

Trivia

 * Its name is a portmanteau between the words usagi (兎, Japanese for rabbit) and hebi (蛇, Japanese for snake). This reflects its appearance as a snake with rabbit ears.
