Jellygnite,[1][2] or Jellies,[3] are recurring enemies in the Sonic the Hedgehog series. They are jellyfish-based Badniks created by Dr. Eggman.


Jellygnites are based on jellyfish; their main body has a pair of eyes and three tentacles sprouting from below their body. 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 lower water sections of the Hidden Palace Zone.

Similar to the Grabber, the Jellygnites have more realistic movements. If a character gets caught in their long arms, it will electrify them and blowing themselves up in the process. Like in Grabber's case, the player can escape the Jellies' grasp by mashing the jump button several times. The player has to hit the Jellies upwards to avoid being electrocuted.

Sonic Mania

Jellygnite HCZ

In Sonic Mania, the Jellygnites appear as enemies in Hydrocity Zone. In gameplay, they act and behave like how they did in the Sonic the Hedgehog 2 2013 re-release.



  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. Craig Stitt, the original designer of the deleted Hidden Palace Zone from Sonic the Hedgehog 2, stated that many (if not all) of the enemies are different, but enemy appearance and behavior were possibly not finalized. To his recollection, he can conclusively confirm that the addition of the boss and organ are new assets and not part of the planned zone.
