The nudibranch seller is a fish citizen who appears in the episode "A Pal for Gary."
She is a light purple fish with light yellow and light green eyes and black hair. She wears a light blue dress, a red cape, and blue slippers. She looks and talks like a gypsy.
She is seen as untrustworthy for her strange appearance and sales of violent creatures, but also cautious, as she does not want the nudibranchs to maliciously harm anyone.
Role in episode
SpongeBob notices the nudibranchs she's selling and immediately gets excited. She tells him that they are rare but extremely dangerous. SpongeBob is too amazed by their appearance and takes a green nudibranch, which he later names Puffy Fluffy. She warns SpongeBob that the nudibranchs are violent and aggravated by other pets. She shows an example, with a nudibranch angrily growling at a picture of a cat, but SpongeBob ignores her warnings and leaves with Puffy Fluffy.
