Bing and Bong arrive on the Tiny Planet of Light and Color, and discover a group of Flockers chasing a rain cloud. When the cloud stops, it rains and a rainbow appears underneath, but then vanishes as another cloud appears and blocks the sun. Bong scurries off to a garden where Bing finds Bong playing in a sprinkler. As a soaked Bong shakes dry, Bing sees rainbows reflected in the spray of droplets. Bing thinks and realizes that the position of the sun in relation to the water/mist is what makes a rainbow appear! Bing quickly sends Bong to assemble the group of Flockers. Once the group positions itself before the sprinkler & sun, everyone can see the resulting rainbow.
