It's the last day of school before the winter holidays and the kids take a trip to Murph's recycling plant. The kids learn how recycling helps the earth in "Holiday special" ; in "All dried up" Phoebe goes on a crusade to save the animals and plants of the desert - and discovers how well they take care of themselves ; in "In the rainforest" kids goes to the rainforest on Earth Day to discover how cocoa pods, mud puddles and bugs all play a part in the wondrous web of life!
