Jellygnite,[1][2] or Jellies,[3] is an enemy in the Sonic the Hedgehog series. It is a mass-produced, jellyfish-based Badnik created by Dr. Eggman.


Jellygnites are based on jellyfish; their main body is a metallic cap with a pair of eyes and three tentacles sprouting from their bottom. Each tentacle consists of four ball segments.

Game appearances

Sonic the Hedgehog 2 (2013)


In the 2013 re-release of Sonic the Hedgehog 2, the Jellygnites appear as enemies. In this game, they are only found floating around in the underwater sections of Hidden Palace Zone.

Similar to the Grabbers, the Jellygnites have more realistic movements. If a character gets caught in their long arms, it will electrify them and blow themselves up a short while afterward (without releasing an Animal) to damage the player. Like the Grabbers, the player can escape the Jellygnites' grasp by tapping left and right repeatedly. To destroy a Jellygnite, the player has to hit it from above to avoid being grabbed.

Sonic Mania

In Sonic Mania, and its expansion Sonic Mania Plus, the Jellygnites reappear as enemies. In terms of design, they look much like how they did in their debut, except their spots are now yellow. In these games, they appear underwater in both Acts of Hydrocity Zone.

In gameplay, the Jellygnites behave just like in their debut game: they swim up and down, and will catch those who get near them before trying to self-destruct. Also, upon destroying a Jellygnite, it will release an Animal.

Powers and abilities

The Jellygnites have an ability to swim. When they manage to catch their prey in their tentacles, they are able to self-destruct to inflict damage to their captive.


  • Being the only new Badnik to be featured in the 2013 re-release of Sonic 2, Jellygnites do not appear in any known prototype versions of the game and were likely an original concept for the Zone's official re-creation.[4]
  • Jellygnite's name may be a pun on "jellyfish" and "gelignite", a type of gelatin-like explosive.


  1. An administrator of the website Sonic Retro asked about the jellyfish Badnik's wiki entry, dubbing it "Jellygnite".
  2. Browsing through the files in Sonic Mania reveals that the Badnik is refered to as "Jellygnite".
  3. Simon Thomley (Stealth), through text, seems to have written "We call it Jellies!"
  4. Interview with Craig Stitt, the mind behind Sonic 2's Hidden Palac (3 June 2014). Retrieved on 24 September 2017. "Craig Stitt: It's been SO long since I last played 'my' version of HPZ that I can't be specific about changes to the level, enemies, music."
