Grandma Plankton is Plankton's paternal grandmother and Plankton's father's mother. She is first mentioned in the episode "Krabs vs. Plankton." She was called Gram-Gram in that episode. She only physically appears in the episode "Gramma's Secret Recipe." She is voiced by Laraine Newman.

Description

She looks similar to Plankton, except that she has glasses, dentures, lavender-colored puffy hair, and wears an orange dress that has green polka dots.

History

She lives in Shady Shoal's Retirement Home along with many other elderly citizens, including Mermaid Man, and Barnacle Boy. Plankton dressed up as her in another attempt to steal the Krabby Patty Secret Formula. Plankton borrowed his grandmother's glasses, her dentures, her dress, and her puffy hair to be SpongeBob's maternal grandmother.
