This is our river. We call it the great seaweed river. We were going to make it a sinkhole but we made it the river. A bunch of sand fell in. We made quicksand too. This is the way we made it: water came in and we stirred up the sand. There was a part we fell in because the water got deep quick.
How long are you going to make this river? Do you have any boats to sail up and down your river?
The water and sand look so nice there. I wish I were there to be part of the fun you must be having.
We didn't bring any boats but if we had we could put them in. I wish you were here too.
