@booksofwonder Mommy? by Maurice Sendak (2006) – Sendak’s only pop-up book has but two words, one repeated several times. A toddler wanders into a haunted house but instead of the monsters harming him, he pranks them – pulling out Frankenstein’s neck bolts, unwrapping the mummy, depantsing the werewolf, and plugging Dracula’s mouth with a binky. Turns out he belongs to Frankenstein’s bride. No wonder!
