Clifford Sneaky PuzzleThis 46 piece puzzle is really 2 puzzles in one. On one side, put together a giant Clifford with his friends and on the other side there's a fun Birdwell Island scene. In addition to the fun of putting together a puzzle, children also experience an educational feature: The letters of the alphabet and numbers 0 to 9 are hidden in the scenery, sneaky, huh? Find them all. Finished puzzle measures 2' x 3', that's humongous.
