She tries to sell a house for Squidward Tentacles, but SpongeBob and Patrick dress up with big noses, posing as the real Squidward, and SpongeBob lies about how horrible the house was when he describes it to her. Eventually, the real Squidward arrived, and Patty said, "What kind of fool do you take me for? He's Squidward? He's Squidward?! You're Squidward?!! I'm Squidward! Are there any other Squidwards I should know about?!," and Gary appeared with a pickle between his eyes. Patty left in a huff, leaving Squidward on the ground sobbing hysterically.
She first appears in the flashback of SpongeBob moving in. She attempts to sell SpongeBob several houses. When there are no more houses, a pineapple falls from a pirate ship into the sea and lands. SpongeBob says that the house is perfect and he gives her a large bag of money.
She later appears in the flashback of SpongeBob and Sandy's fake wedding. She appears with the crowd when they leave the Recreation Center.
