Dinosaur doesn't need to use the potty.
Even when he's making lemonade, running through the sprinkler, having a three-juice-box lunch, and splashing in rain puddles. See? He's doing his victory dance. Wait . . . that's not a victory dance, that looks like a POTTY DANCE! Run, Dinosaur, run! Can he make it in time? Potty wins! Close one, Dinosaur. Real, real close.
