Medusal Slurker

Fighting the Medusal Slurker. If you look closely you can see the Rock Pikmin floating inside of it

The Medusal Slurker is an enemy from Pikmin 3. It is the first enemy of the game and appears right after you break the first wall. It will fly around the area in order to avoid any Pikmin thrown and will attempt to shurg them off if any latch on. After defeated, it releases Rock Pikmin. It slightly resembles a Lesser Spotted Jellyfloat or a Greater Spotted Jellyfloat.
