The Pond Stars create a pond for rescued turtles, to be used as an outdoor classroom for an upcoming kids camp. Greg and his guys build a 35-foot waterfall and 600 gallon, underground reservoir that will have wildlife flocking to a suburban backyard.

The team starts in the California mountains where they attempt to replicate a brown trout stream in a client's backyard. Then, the guys head to Los Angeles, where they are asked to create a healing garden for a brave cancer survivor.

In Florida, the guys must race the clock, and face construction challenges they've never seen, all while trying to blend two unique backyards with the wetlands and coastal ecosystems surrounding them.

The crew installs a giant, natural pond in Tony and Shari's backyard to provide a larger home for their koi fish. Their koi have grown obese from an incorrect diet, so the crew must also design a koi treadmill so these fish can lose their belly fat.

The Pond Stars head to the world-renowned Lincoln Park Zoo for two projects. At the Red Wolf exhibit their solution requires a massive overhaul. Then a small job at the bird exhibit turns into a total re-do and they only have 4 days to get it done.
