Role in episode
Pearl and her friends all think she is SpongeBob in disguise, so they throw tomatoes at her, but it is shown that she is not him because as she is running away, the real SpongeBob and Mr. Krabs immediately drive up and have no idea who she is. Her part ends when she screams stating about how she is moving back to Farawayville. At that point, Mr. Krabs asks who she is, whereupon SpongeBob replies by saying he does not know but thinks she is ugly.
In the Dutch version, she is called "Spongy Betty."
Instead of saying "I am so moving back to Farawayville!," she says, "Ik voel me zo niet gewild!" ("I feel so not wanted!") in this version.
In the Chinese version, she is called "Bad Ugly Girl."
