S1·E15 Hide and Seek

'You need to pee-pee before you play, or... stop the game and do it. So you're all dry when you're finded again'.

Bing plays hide and seek at the crèche with Sula, Pando and Coco. He didn't go to the toilet with all the others before the game started and now he has to decide whether to give up his hiding place or try and hold on.
