Tiny Planets It's Raining Bongs

On the Tiny Planet of Nature, Bing and Bong learn how the water cycle works. First, they see water go through the natural cycle of becoming steam, then clouds, then rain, and, finally, river water again. They then encounter a river being drained for a Flockwash, and only after they redirect the run-off back to the river does the river begin to flow normally once again.
