I suppose this would count as a toy, though a big one! It seems to me that we (American civilization we) are more likely to spend big bucks on creating a room for our child than buying very expensive toys. This might count as an outdoor room.
Imagine your back yard being the place where your tots could plot and play all day.
Heck, I'd spend the night here - often. It even has a built in bed.
Called "Red Beards Revenge" it could be yours here for a mere $52,000 plus shipping.
Maybe you're handy enough to build something like it for less?
