Shelly Smith Shenoy (Season 1) and Sharon Mann (Season 2)
She is a possessed marionette/puppet/ventriloquist dummy and a member of Thatch's gang. Her special "creature" power is her ability to be funny, although the other students said they wouldn't be able to tell if she lost it, meaning they probably don't think she's that funny. She has a crush on Slither.
Dummy Girl is made of wood. She has long navy blue hair (with black highlights) tied in two pigtals with large red bows, red eyes and has blue eyeshadow, pink colored cheeks and red lipstick. She wears a navy blue shirt with a skull on it, a red skirt, white and red striped socks and brown boots.
She tends to be annoying and likes to make fun of others.
