|It must feel nice to float around all day. Beware of its stinging tentacles!|
— Patch Plaza
Sea Jelly is a large floating jellyfish-like enemy from Kirby's Epic Yarn and Kirby's Extra Epic Yarn. Despite its name, it is not found underwater, instead floating in air, where it will release spores. These spores cannot harm Kirby or Fluff, but if they connect, they will be immobilized until they can shake the mushrooms off.
- The description and name for this enemy is misleading, as it is not found in the sea, and does not have dangerous tentacles. These descriptions are more accurate for Jelly Jr..
