|First||First Appearance: Terrence: Halloween Thriller Night|
|Third||Affilation: Brock High Students|
|Sixth||Voice Actor: Kate Higgins|
She was one of the students at Brockton and she was helping putting the decorations for the Halloween celebration. She and the others were chased by Volf and his pack, only to be saved by Terrence and they became his friends.
She was seen at school again only to see Terrence and Majestic Guardians, who were on a mission to stop Devatan, the Destroyer.
She's very friendly, sweet and polite, but a bit clumsy. She's the most naive of all the monster girls. She tried to learn few things by looking through Monster magazines, althought it caused awkward moments for her.
She has black hair with white streak, light mint skin and heteochromia eyes- one green eye on the right and one yellow eye on the left- visible stitches all over her bodies and two bolts on her neck to absorb electricity. She wore a green and black plaid dress and black and white shoes.
