She has light purple hair and a bright turquoise green dress. She is a slightly brighter pink than the other starfish seen in the series.
She appears in the episode, I'm with Stupid when she and Marty decide to visit Patrick's house for Starfish Day. Patrick tells them he's a genius and SpongeBob's his moronic neighbor, just to impress him and they buy it.
Unfortunetly, Patrick starts milking the moment and starts mistreating SpongeBob. SpongeBob decides to tell the truth, but Janet and Marty still think Patrick's smart (being stupid, themselves) and laugh at SpongeBob. SpongeBob screams at the top of his voice and runs out the house.
When Janet and Marty reveal their true names, Patrick realizes that they're not his parents and decides to interogate them, but before he can, Squidward arrives with another starfish couple and Patrick realizes that they're his parents. Marty and Janet remember they don't have a son and leve.
"Marty, I'm scared!"
"It looks like it's time for your next lesson, young man."
