Mr. Green Turtle (ミドリガメくんin Japanese, Mr. Scaly Green or Mr. Green Turtle in the English dub) is Kodachi Kuno's giant pet crocodilian. He wears an electrified pink collar around his neck that reads his name. This collar is made of 'memory metal' that cannot be removed without receiving a painful shock. Splashing it with hot water nullifies the electric field and allows it to be reshaped. It also contains a small hidden compartment. Kodachi once used the collar to stash the negatives for some photographs Hikaru Gosunkugi (in the anime, it was Sasuke Sarugakure) took that displayed her and Ranma having what appeared to be an intimate moment, forcing the latter into a fight with her pet.
