Ukulele Pichu (Japanese: ウクレレピチューUkulele Pichu) is a ukulele-playing Pichu that serves as the partner Pokémon to Ben or Summer in Pokémon Ranger: Guardian Signs. Its physical appearance is no different from an ordinary Pichu, other than the fact that it carries a ukulele on its back. The ukulele that it carries was is made by Booker out of wood from the leftover parts of a boat, as mentioned early in the game, but after one of the Pokémon Pinchers breaks it, Booker makes a new, stronger one for it out of a special type of wood.
Ukulele Pichu also appears in Pokémon Ranger: Guardian Signs, where it is the player's Partner Pokémon. The player encounters Pichu in Dolce Island where it is playing its ukulele to its friends. Unlike a regular Pichu, it has a different Poké Assist. When the player calls it in a capture, Pichu would come to the field and play its ukulele to make the capture easier. The tune it plays on the ukulele will become stronger the more the player passes through gameplay.
