Blue's Big Treasure Hunt. When Mailbox provides Steve with a package, it turns out to be a treasure chest, introducing ""Blue's Big Treasure Hunt."" Throughout the episode, we search for both clues and treasure hunt hints (scrolls of paper) to lead us to our goal. We solve riddles for clues and even find secret compartments. We even get to skiddoo into the Land of Great Discovery, where we help out characters from favorite nursery rhymes to remember just what happens in their rhymes.
