Track down Twyla!

"When the ghouls receive a mysterious message from the daughter of the Boogey Man, they decide it's time to bring another monster home to the new Monster High! But nothing is quite as it seems in the creeperific Boogey Mansion. As they wander through a maze of rooms filled with tricks and treats, Frankie Stein, Draculaura, Clawdeen Wolf, Cleo de Nile, and Lagoona Blue don't know which way is up, down, or sideways! All they know for sure is that this is going to be one fangtastic adventure!"--Back cover.
