About Plankton's voice

Sheldon J. Plankton is the tiny one-eyed villain of SpongeBob SquarePants who runs the failing Chum Bucket and schemes endlessly to steal the Krabby Patty secret formula, with his computer wife Karen. He is voiced by Mr. Lawrence. His voice is nasal and grandiose, swinging from scheming whispers to triumphant villain cackles and frantic, squeaky outrage when his plans fail.

Tips for the best Plankton audio

Write grand villain declarations about tiny goals, like stealing cookies or winning a board game; Plankton's comedy is huge ambition at small scale.
Add mwa-ha-ha or ha ha ha for his cackle, and address Karen or Krabs to keep the SpongeBob world alive.
