A single music piece devoted entirely to Magikarp, the Pokémon known in Japan as Koiking. The song was made as a joint promotion that linked Hiroshima's baseball team, the Toyo Carp, with the city's Pokémon Center store, pairing a local sports club with one of the franchise's shops. The whole track keeps its focus on that one Pokémon, making it a novelty song for Pokémon fans.
