From the Super Mario Wiki
Georgette Jellies are blobs of goo that move slowly on the ground. They are found in the game Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. Georgette Jellies cannot be turned into eggs by a Yoshi, and stepping on them only makes the goo creatures splatter on the walls. After a few seconds, a spattered Georgette Jelly will fall off to the ground and reform. If slurped and spat out, these creatures make makeshift projectiles.
Georgette Jellies only appear in Sluggy the Unshaven's Fort.
