She is a light orange fish with a dark orange dorsal fin and wears a blue dress and dark blue earrings. She has dark pink lips. She is blue in "The SpongeBob SquarePants Movie", bright orange in "Whale of a Birthday," and yellow in "The Slumber Party."
She thinks that Mr. Krabs is lame because Pearl's parties are so cheap, such as sharing a balloon, or having paperclips as party favors. She calls SpongeBob the "Really Tall One," in "The Chaperone." She loves to go shopping. She isn't always nice to Pearl, as seen in "The Chaperone," when she helps throw her and SpongeBob out, "Whale of a Birthday" when she frequently makes fun of her boring parties, and "The Slumber Party" when she says she won't be her friend anymore if SpongeBob turned into a zombie and ate her brain.
