It's dinnertime at the annual feast for fiends-lift the flap covering each monster's plate to reveal the deliciously gruesome meal underneath in this grossly funny picture book. Bone Appétit! You're invited to the annual feast for fiends! Up on a rocky hill lies The Rotten Core Restaurant, where monsters from all over have gathered around the dinner table to enjoy the best foods the dastardly chef (and his undead maîtres d') have to offer. Lift the plate cover to reveal the terrifyingly tasty meal underneath. For the vampire? Chef's famous scarlet smoothie and thinly sliced bat wings start the meal, and a few princess necks are a main course that's to die for! For the witch? Snail-slime porridge, and an apple dipped in black widow venom for dessert! Other monster guests include a werewolf, an ogre, a mummy, a pirate, the monster under the bed, and even the Boogeyman, all with delightfully disgusting dishes cooked perfectly to their tastes. But it might be the final guest-a small human boy-who has the most terrifying tastes of all. With 10 sturdy flaps readers can flip up to reveal a ridiculously revolting menu underneath, this picture book is sure to have young readers laughing out loud and eager to curate a monstrous menu of their own!
