Let's journey with Sally and Nick and the Cat... To learn a little bit about weather, imagine that! First, the kids are painting a picture of a rainbow but can't seem to remember all the colors to use. Lucky for them, Cat takes them to Color-ga-lore to meet King Kaleidoscope, a rainbow expert. A musical number teaches them the proper color order as well as how rainbows are actually made! Then it's time to jump in some puddles with Nick and Sally! But wait, where did the giant puddle disappear to? With the help of Cat's Seussian camera, they see that their puddle has turned into water vapor. So off they go to Bluey Blue Sky to follow their puddle. They learn the water cycle process and when they return home their puddle is back! Weather is just the start of this trip with the Cat So come on board the Thinga-ma-jigger and hold onto your hat!
