Janet is a character from the SpongeBob SquarePants TV series. She is Patrick Star's fake mother. She only appears in the episode "I'm with Stupid." She is a parody of Marge Simpson from the series The Simpsons, as she has hair like Marge's (though Marge's is blue) and has a croaky voice like Marge's. She is married to Marty. Strangely even though that they don't have a son, they seem to know a lot about Patrick. They could be some sort of stalkers or people who have found information about him.
She has purplish hair and a bluish green dress. She is a slightly darker pink than the other starfish seen in the series.
On a CD, she is named "Fake Mom."
"Marty, I'm scared!"
"It looks like it's time for your next lesson, young man."
