Hi! You may know by now that Dav Pilkey, the creator of the Captain Underpants series has a new book out called The Adventures of Ook and Gluk: Kung Fu Cavemen From the Future. There were some hilarious comments about the book cover when we previewed it a few months ago. And now Dav Pilkey created this Spot the Difference game with an image from the book. There are 26 differences between the two images. Can you find them all?
Have fun and tell us what you think in the Comments. For more fun stuff from Dav Pilkey, check out the Ook & Gluk website.
