Balloons They are the favourite playthings of Princess Leora. When her father, the king, goes to a neighbouring kingdom to participate in a tournament, he tells Leora to signal him with balloons if anything goes wrong. But the archduke, planning to take over the kingdom, promptly locks the princess in her room and orders all the balloons in the kingdom to be popped. With the help of a wizard and a boy with the only balloon left in the kingdom, Leora is able to plant a balloon tree that blossoms into thousands of balloons. But will it be in time to save the kingdom?
