Pikachu's Song (Japanese: ピカチュウのうたPikachu's Song) is the sixth ending theme of the XY series. It debuted with XY129, replacing Puni-chan's Song, and was released as part of the XY&Z TV Anime Character Song Project.
Ash's Pikachu sings as he climbs a giant bottle of ketchup. More Pikachu appear with similarly large bottles of ketchup, and they sing with him as they dance around various bottles of ketchup that appear in different sizes and even growing on plants. Finally, Ash's Pikachu finds a plant that quickly grows into a massive ketchup tree.
