I had the misfortune of owning a Willy Water Bug as a child. Willy Water Bug was a water toy with a bug-shaped body about 3 feet tall with striped plastic tentacles protruding from its body. It was connected to the garden hose and water would spray through the plastic tentacles causing them to menacingly flail around in search of young children's flesh. I think I used it maybe twice, but have spoken of it often.
I would try to jump over it and it would whip my legs with those horrible tentacles. It wasn't fun at all, but painful. If you left Willi hooked to the hose two consecutive days in the hot sun, those tentacles became like hot knives cutting through butter. There's nothing worse than being whipped with hot plastic.
When my mother offered to set up Willy in the backyard, I would always politely decline.
