Fan Casting Ghoulia Yelps in Monster High

Ghoulia is depicted as intelligent, sophisticated, timid, overworked, and shy. She's a huge bookworm and is very intellectual; all of her fellow students call her the smartest ghoul at Monster High. It is revealed in her diary that she is good friends with Cleo de Nile because Cleo was willing to give her a chance, as zombies are typically discriminated against. Ghoulia can be very unhappy with Cleo often though because of her intelligence.
