To celebrate a birthday you need: one hundred guests to send one hundred letters to, some cloud scrioppo prepared by Aunt Goose, food for guests who are always hungry, a bored frog that can make everything even more bubbly (literally). And also traveling donkeys and gentle elephants, foxes in love with unlucky geese and hordes of wild dogs.
The next morning, however, there is an urgent desire to clean everything up... poor Little Bear!.
