Shounen Ashibe: Go! Go! Goma-chan

'Shounen Ashibe: Go! Go! Goma-chan (alternatively spelled Shonen Ashibe or Shōnen Ashibe') is a multimedia franchise spanning various media, including anime and manga. Beginning in 1988, the series always the same plotline of a boy and his pet seal, albeit with new art styles appearing across the media forms and with many new increments upon the story occurring over time.

Anime
The first well-known medium of Shounen Ashibe (and perhaps the best-known of its form) is its foray into anime. Originally made as an anime in 1991, Shounen Ashibe was remade on Crunchyroll as yet another anime version beginning in 2016. This later anime version currently has 109 episodes, with new ones releasing every Tuesday.

Manga
The very first medium that Shounen Ashibe debuted in was manga, starting in 1988. This first manga was adapted into the first anime in 1991. 25 years later, the pattern would be reversed when a new version of the manga began releasing in 2016, this time based on the anime that had just started a month prior. At the moment, this new manga has 22 chapters, released on an irregular schedule (often many at once).
