Nature Cat and his pals are at the beach playing a game of catch when their flying disk accidentally lands on top of a sandy hill. Whoopsie! As they all start to race up the hill, a cute little Plover stops them in their tracks. She explains that the sandy hill is actually a sand dune and it's very important and needs protection. Nature Cat and his pals promise to make sure that no one ruins the sand dunes. Dune Patrol, ho!!
