Monster High Secret Critter Pet Collection: Pets can be the best friends and the best secret keepers. The pets of the core Monster High ghouls have come to unlife to keep your secrets! Each of these five scary cute sidekicks (sold separately) has a secret-keeping feature. Count Fabulous (pet bat of Draculaura) and Neptuna (Lagoona Blue doll's piranha) figures come with one invisible ink pen along with paper and a "reveal" feature. Write in secret- or in the open - but expose your thoughts only when it's safe! Captain Penny (robotic penguin of Robecca Steam), Azura (Nefera de Nile doll's scarab beetle) and Hissette (cute cobra of Cleo de Nile) figures each come with a basic pen and paper that can be used along with their secret-keeping and note-passing features. Share secrets with your pets and your friends! Each sold separately, collect them all!
