Bright Eyes brings to her friends' attention the current garbage pollution problem. They divide into teams to track down the responsible dumpers but they are not using their common sense and do their own littering. As a result Pony River gets clogged and floods the surface. Whilst the grownups unclog the river, the girls see the trash they threw previously and fully realise their carelessness and begin cleaning up. Episode Song: "A Lot Less Litter", sung by the girls.
