The Thing That Broke

S1, E24: Tony discovers a big round and invents the brilliant game of bigging and rounding! He runs on the top of the huge rock making it roll - like a unicyclist. It looks like the most fun ever so Bob and Gwen join in. Our trio race through the landscape atop their new toy having the time of their lives until it hits a rock and they’re sent flying through the air. The Dinopaws land to see their big round broken into three pieces. They try to put it back together but they can’t and they give up.
