Tanis is a young mummy, who attends Miss Grimwood's Finishing School for Ghouls.
Tanis is the youngest and the shortest of all the girls. She has blue eyes, white skin, and she wears a plain white dress and wears a dark pink bow on her head, and the bandages on her head resemble a ponytail.
Because she is so young, Tanis has a childlike personality, and is usually a very happy girl. As the youngest ghoul, she has the most innocent mindset, as shown by her habit of sucking her thumb.
Scooby-Doo and the Ghoul School
She gave her Mummy Daddy a "Fright Light" shaped like a mummy case with a mummy figurine inside that gives off red beams out of it's eyes when it opens, "to brighten the darkest mummy case."
Tanis: Are they the new gym teachers?
Tanis: Careful, Winnie! You're tapping on my wrapping!
Tanis: I want our Scooby-Doo back!
- Tanis's voice actor, Patty Maloney, uses a very similar voice to Darla Hood's from the 1982 Little Rascals animated series from Hanna-Barbera.
