The Worthless Protoplasm is an enigmatic enemy encountered in EarthBound. They are found in Brick Road's first dungeon, and appear in the Fourside Department Store after the lights are shut off. They reappear on Dungeon Man's first floor.

In the overworld, they appear as a Present. In battle, they appear as blue-purple slimy creatures with beady black eyes.


Worthless Protoplasms, true to their names, are weak foes that can easily be beaten, as they have low stats, and their only action, self-inducing a strange feeling.

A reference to the Worthless Protoplasm is made during the battle with Negative Man in Mother 3. During battle, the Negative Man may waste a turn by saying "I'm nothing but a worthless protoplasm..."
