Join Mack, a blue moose with a heart of gold and two left feet, and Moxy, a perky pink raccoon, on four new exciting adventures! Watch Mack & Moxy rescue another Great Helpee in a far off mystical place called HelpeeLand. In the first adventure, Mack & Moxy start a lively game of foursquare at the HelpeeLand School. When a disagreement develops over who won, Trooper Sydnee suggests Rock, Paper, Scissors to settle the dispute. It works like a charm except for one problem Shelfish Sheldon (played by Hank Azaria) is about to snatch the Great Helpee and keep all it's happiness for himself. Guest celebrity, Simone Biles (Olympic Gymnastic Gold Medal winner), helps the Heroes on their mission. Three more adventures introduce kids to subjects like autistm, buckling-up for safety and eating healthy foods.
