Ha-huh! Amazing! Three minutes in the kitchen and our son has taught him to talk in complete sentences. Oh, good work, son!
— Marty after hearing SpongeBob talk proper sentences, "I'm with Stupid"

Marty is Patrick's fake father. He only appears in the episode "I'm with Stupid." Marty is married to Janet and comes to Patrick's house for Annual Starfish Day.


He is a reddish-pink starfish who has bushy eyebrows and wears a gray tank top and blue shorts. He is a darker shade of pink than most other starfish in the series.

Role in episode

SpongeBob pretends to be dumb for Patrick's fake parents. He is not quite smart himself though.

Even though SpongeBob reveals the truth about Patrick, Marty and Janet still don't believe Patrick is dumb and start laughing at SpongeBob, who runs out of the house in a fury. When Janet and Marty reveal their real names, Patrick gasps and demands to know who they are.

Before Patrick can do anything, Squidward arrives with another starfish couple, who reveal themselves to be Patrick's real parents. Janet and Marty realize they don't have a son and leave.
