Moongobble has successfully completed two of his three Mighty Tasks: He's collected the Golden Acorns of Alcoona and bottled the tears of the Weeping Werewolf. There's only one more Mighty Task to go, then Moongobble will become a member of the Society of Magicians. But this might be the most difficult one of them all. Moongobble must go deep into the Forest of Boodle to recover the Queen's Belly Button, a magical stone that was plucked off an ancient statue by a band of elves. The Belly Button has the power to tempt its owner to do evil things -- and those elves have been causing trouble left and right. Moongobble enlists the help of Edward, Urk, the Rusty Knight, Fireball the Dragon, and Arfur, an old friend. Even with their help, this task won't be easy. Anyone who attempts to steal the Belly Button and fails will be turned into stone Will Moongobble be able to successfully steal the stone and resist its powers?
