Hissette is Cleo de Nile's pet cobra.
Hissette is a light blue Egyptian cobra, with all sorts of funky jewelry on her neck, a small crown on her head, and a small ring on her tail.
"Her hiss is, honestly much worse than her, er, somewhat poisonous bite"
'Basic' Hissette is curled up in a sitting position.

- In The Ghoul Next Door, Hissette was a gift from Deuce, to Cleo. Deuce said that Hissette was his mom's "first gray hair". Also for a good part of the book, she was turned to stone, and Cleo wore her around her right bicep. However, in Cleo's diary, and thus the doll universe, it says that she was sent from Egypt.
