Remote intended to be made from plastic and rubber.
Croquet hoop design made from wood, PVC, and gripping tape. Two people are able to grab a pole and twist which rotates the wooden pegs at the bottom. These two people serve as a goalkeeper while a third person tries to hit the ball through with the croquet mallet. I call this "croquet pinball".
