Nukky

Munki is a Sea Raccoon belonging to Lina. Munki and his master appeared during the Spa Island Arc. Members of Munki's species can change their appearance to whatever they want, such as animals, people and objects, however all the things he changes into must be the same size as him, if they are larger than him he will instead change into a miniature version of the thing he imitated (such as when he transformed into Nami).
