ゲラゲラポーのうた (Gera Gera Po no Uta) is the debut single by the fictional unit キング・クリームソーダ (King Cream Soda), created for the multimedia Yo-kai Watch franchise. The song served as the first opening theme for the Yo-kai Watch anime series, which premiered in January 2014. Its composition and arrangement were handled by Tomoki Kikuya, a prolific anime composer, while the lyrics were penned by Motsu, best known as the lyricist and MC of the group m.o.v.e, whose contributions to the Initial D soundtrack include classics such as "around the world" and "Rage your dream." The track was added to maimai PiNK at the arcade version's launch on December 9, 2015, within the POPS & ANIME genre. The in-game background video uses the Yo-kai Watch anime's opening animation, matching the song's cheerful, bouncy tone. The Master chart, designed by はっぴー (Happy) and rated level 9+ with a constant of 9.6, stands out for its 57 Slide notes, a relatively high count for its era that gives the chart a flowing, dance-like character. The Expert chart was designed by Techno Kitchen. ゲラゲラポーのうた was removed from all maimai arcade cabinets on June 21, 2018, during the MiLK version era, and was never carried over to the maimai DX series. The song also appears in Bandai Namco's Taiko no Tatsujin rhythm game series.
