The Jellyfish is a transparent sea creature with tentacles that extend and sting. They appear in Yoshi's Story and the only level appearance is Lots O' Jellyfish.
They come in three colors which determine their attack pattern and behavior red, blue and green.
- The blue ones move up and down in the area they remained fixed to never leaving the area they are found in.
- The red ones can move around freely where they can actually pursue Yoshi and his allies if they spot them.
- The green ones behave similar to the blue ones expect they do not move up and down and remain stationary at all times all variants can sometimes have fruit inside them as well.
