Jellyfish (Yoshi's Story)
From the Super Mario Wiki, the Mario encyclopedia
Jellyfish are enemies from Yoshi's Story that only appear in the level Lots O'Jelly Fish. They are impervious to all methods of defeat and come in blue, red, and green. Blue jellyfish simply move up and down. Red jellyfish chase a Yoshi. Green jellyfish simply float in place and do not appear until the third part of the stage. Red jellyfish can sometimes have an item like a fruit or a Heart Fruit.
