Mary is an elegant and posh snail. Her owner is Monica. She looks very much like Mrs. Puff's snail and Snellie. Her shell is lavender, with a dark purple swirl. She has a bow that is red with white polka dots on the top of her shell.
She liked Gary for a short time; however, her current love interest is Brad's snail, Billy (who says "meow" like a human would).
