Kirby Mass Attack sprite
Shellmic resembles a green, reptilian monster with a raspberry red mouth, small eyes, and a spiky head.
Shellmic appears in underwater levels where it sleeps inside of shells. If a Kirby bumps into the shell Shellmic is sleeping in, the Shellmic will wake up, pop out, and try to suck the Kirbys towards it and touch its spikes. If any Kirbys touch it, they will get hurt and the Shellmic will smile for accomplishing this, so the Kirbys will have to swim away. It can only be defeated once it goes back inside its shell; the Kirbys must slam into it three times before it breaks.
Shellmic also has a cousin known as Glub, who mimics the same attack, but doesn't hide in shells—though a Glub's attack will instantly KO any victim Kirbys. However, Glubs can also exhale to blow the Kirbys away from it, while Shellmic can only inhale the Kirbys.
Shellmic is a portmanteau of shell, the obtain the enemy hides in, and mimic, referring to it pretending to be a shell until a Kirby bumps into it.
