Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

This is the first time that Winnie the Child of the picture book
has been invited to a human birthday party. I'm happy, but I don't have any clothes to wear and I don't have anything to give as a present, so I can't decide what to do. Then, I went to talk to my friend, Tamami-san, who made a wonderful proposal. Winnie the Pooh is relieved. But on the morning of the party when I was all ready, my heart throbs and my stomach hurts, and Winnie the Pooh feels restless again. What should I do?
