I've been unable to locate this little mobile game I used to play on my Nook tablet (it may have even been a Nook exclusive). It was a free, puzzle-solving game for kids that I believe revolved around the player who was described as "average" working to free his city from being encased in stone (or something to that effect). One of the specific puzzles that I can recall was a level where you had to correctly alphabetize a bookshelf full of misplaced books. One detail that I hope can help is that most, if not all, the characters/locations had a pun ending with the word, "watts". For example, there was a character named Mr. Big Watts who was designed and voiced to parody Marlon Brando's character, Vito Corleone, in the Godfather. The only other thing I can recall is that the game ended in a tree house and there were two possible endings.
