Sheldon J. Plankton

Sheldon J. Plankton is the main character of Lucy's Cartoon Pals.

Personality
Plankton is an evil mastermind through and through. His plans always involve technological devices and weapons, all for the sake of the formula. His main goal has always been throwing the Krusty Krab out of business.

Appearance
Plankton is, as his name suggests, a tiny dark green-colored plankton who can fit in the palm of one's hand. He has stubby appendages and one yellow eye with a red pupil. He has two long, skinny antennae with small green spikes sticking out along them. He also has one black eyebrow.

Trivia/Facts

 * Plankton is left-handed.
 * There is a running gag in many episodes he appears in (including the movie) where he is squished by a person. Another running gag is him being projected through the air back to the Chum Bucket, typically by Mr. Krabs, often screaming a sentence or a prolonged word meanwhile.
