I knew I had seen these somewhere and when I looked at home depot, they had them! Of coarse two days after having it, it got stepped on by my niece and it cracked all the way down the middle. I have since then kicked it multiple times and my son has now discovered it. It is pretty much done for. I thought, its time to throw it out and get a new one, someone could get cut. Then I thought, why not use cardboard, its free and easy to make as many times as I need to!!
