Several pictures of jellyfish.

Jellyfish are creatures found in Splatoon and Splatoon 2. They can be found walking around Inkopolis, wearing various articles of clothing. The series' jellyfish highly resemble real-life jellyfish. However, the jellyfish in this game are highly anthropomorphized to the point of having eyes and being bipedal, likely from similar evolutions to those of the Inklings and Octarians.

Notable individuals


Main article: Jelonzo

Jelonzo is a blue jellyfish who owns Jelly Fresh, a clothing store in Inkopolis. Most jellyfish in Inkopolis cannot speak the Inkling language; while Jelonzo is an exception, he is only able to speak Inkling with a thick accent, which the English localizations, translate as Engrish.


  • Jellyfishes are featured in most of the arcade games.
  • Marie of the Squid Sisters references this species in advice for Arowana Mall: "Float like a jellyfish, sting like a… jellyfish?" Because the stores and restaurants in the mall are themselves filled with jellyfish, this mention may have been an intentional joke, not a coincidence.
  • Jellyfishes can be found in most of the stages in Regular Battle, but are absent in Ranked Battle.
  • By turning into a squid, a player can go through jellyfish's tentacles in the Plaza.
  • In Splatoon 2, the Jellyfish change colors during Splatfests to correspond to the team colors.
