Find a stream in a forest or a park. If it's not good for swimming in, there are lots of ways to play nearby.

• Float things down the stream and race to see who wins. I always win when Dex tries to float his pet rock.
• Look for cool stones in the water. Try to find ones shaped like celebrities' faces.
• Use rocks, sticks, and leaves to build a dam or reroute the water. Panama Canal, here we come!
• If the stream is small enough, build a bridge over it. Then see if Kitty will cross it.
