Following the success of THE CRANIUM BIG BOOK OF OUTRAGEOUS FUN! this newest wave of books invites children to celebrate their talents - and discover new ones! With alternating rewritable pages and more than 150 all-new activities designed for both solo and group play, each book offers them hours of fun. In Word Worm's book, children will enjoy hours of wacky wordplay, riddles and rhymes using their Word Worm Letter Cubes. In addition, it has other components, including: an erasable marker, Cranium Clay(R), a Mini Sand Timer, 25 Game Cards, a Die and a Game Piece. Also, hidden within it, is a secret slide-out game board and a unique acetate game sheet. As children collect all four Cranium sets, they can mix and match their BOOKS OF OUTRAGEOUS FUN to create new multi-layered games.
