After performing "Hottottotto na Mainichi" in Kigurumichiko, Kigurumi, who had only one member at the time (Rena), was given the opportunity to sing the opening theme to Tamagotchi: The Movie.

The song was released with two different albums, and was slightly edited and used for the intro of "Tamagotchi: The Movie".

Occasionally, they will sit on white inflatable balls, appear on TVs, or watch a scene from the movie.

An English version of the song was written by Stephanie Sheh for the English-language release of "Tamagotchi: The Movie".

Another difference is that the second and fourth lines of the Japanese version of the song end in "ī deshō", which roughly translates as "it's great".
