The show opens with the Balloon Change Relay, a funny game where the ZOOMers race to put on winter clothes and keep a balloon in the air. Then viewers get to find out What's Up at Yellowstone Park! Emily and Francesco make Jungle Bars, a tasty-healthy-high-energy Znack. In ZOOMsci, the kids build a survival raft out of cups and balloons. Can it keep Taylor dry? Jim and Judy return this season, and, as usual, Jim's confused-this time at the movies! And in ZOOMplayhouse, the ZOOMers go on Gross Factor. Who's not grossed out by the Rat Box?
