Zoboo realizes that plants and trees are as alive as all the creatures he meets in Animal Junction. The Kratt Brothers teach the lemur that plants grow well if they get good soil, lots of sunlight and enough water. And there are plenty of creatures willing to help plants flourish, including Toothbrush the elephant, Popcorn the binturong and a whole family of sloths. When Martin and Chris follow Popcorn to India, they visit a 2,000-year old fortress, where green creatures like vines and plants are taking over the site.
