Snellie is a snail who has a lavender shell with a purple swirl on it. She also has a large pink bow tie on top of her shell. Her eyes are pale yellow and have blue irises with black pupils and long black eyelashes.
Snellie's snail carrier is a collectible item in the video game SpongeBob's Truth or Square. When it is viewed in the hub, Snellie's eyes poke out, along with her meowing, before they see each other and go back into the carrier. In the DS version, Snellie herself replaces the item.
Her name may be derived from the Dutch word "Snel," which translates to "Fast" in English.
