Jellygnite

Jellies, or Jellygnite, are enemies that appear in the 2013 re-release of Sonic the Hedgehog 2. They are jellyfish-based Badniks created by Dr. Eggman.

Appearance
Jellies 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.

Overview
Jellies, as an exclusive enemies to the 2013 re-release of Sonic the Hedgehog 2, are only found floating around in the lower water sections of the Hidden Palace Zone.

Similar to the Grabber, the Jellies 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.

Trivia

 * Being the only new Badnik to be featured in the 2013 re-release, Jellies do not appear in any known prototype and were likely an original concept for the Zone's official re-creation.
 * Just like Grabber, the Jellies' Animal will not be freed if it self-destructs.
