|— Cast Description • Kirby's Epic Yarn|
Sea Jellies look like giant orange jellyfish with four white tentacles and purple and yellow button eyes.
Sea Jellies do not usually attack Kirby, but rather hinder his ability to move by creating spores. If these spores touch Kirby or Prince Fluff, they will be unable to move until they shake the spores off. This makes Kirby and the prince vulnerable to enemy attacks such as Waddle Doos, Shelbies, and Buttonbees. If Kirby stands on one of them for too long, however, they will electrify themselves, which is a very short range area attack. Getting close to one or using the yarn whip on one during this time will cause Kirby or Prince Fluff to get hurt.
- Even though they are called Sea Jellies, they are never seen in the ocean.
- In the official Prima guide, these are mistaken as Spore Jellies.
