Mrs. Puff's snail - In "The Sponge Who Could Fly" Mrs. Puff's pet snail is similar to Snellie. It is unknown whether that is Snellie herself, a different snail but with the same body color and shell color, given to Ms. Puff by Squidward (this is proven false for Mrs. Puff claims to have had her since she was a little girl, and Squidward got Snellie in the series), a twin to Snellie, or if it's just a coincidence.
