A magical drop sees that water sources around the world are drying up and decides to teach a boy named Michael about conserving water. The drop shrinks Michael down to its size and takes him on a trip around the world to see the lack of water firsthand. Michael is dismissive of the issue at first but comes to understand the drop's message after returning home to find no water. The drop agrees to return water to Michael's house if he promises to stop wasting water from that point on.
