She looks similar to Squidward's temporary pet, "Snellie" in the episode, "The Great Snail Race" and Mary from "Gary in Love." She has light blue and light green skin and a lavender shell. Her shell also has a dark purple swirl along with a pink bow. She has dark blue eyes and eyelashes.
Mrs. Puff's snail was seen stuck high in a tree somewhere in Bikini Bottom and was seen to be close to falling until SpongeBob rescued her. She was mentioned to have been adopted by Mrs. Puff since Mrs. Puff was a little girl.
There could be a possibility that she is related to Squidward's temporary pet, "Snellie" because they both look similar and with the same looks, their genetics will most likely be similar.
