小熊默里要和姐姐莫莉一起去瀑布见一个朋友，但是默里很担心。“如果它太吵了怎么办？”，“如果我被冲走了怎么办！”于是莫莉向默里说了自己特殊的忧虑箱。“当我担心某件事情时，我会把它写下来，然后把它放在忧虑箱里面。”她提出要帮莫里做一个，他可以在旅途中带着它——但这真的有用吗?

Murray Bear is supposed to go to the waterfall with his sister, Molly, to meet a friend, but Murray is worried. "What if it's too LOUD?" he cries "Or what if I get swept away!" So Molly tells him about her special worry box. "When I'm worried about something," she says, "I write it down, then put it inside." She offers to help make one for Murray, and he takes it on their journey-but will it really help?
