Three friends – Robot, Chicken, and Worm – decide to open a birdhouse city. Everything is ready for the opening: birdhouses are already waiting for their tenants in a beautiful clearing. The friends decide to make the opening a grand affair – with music, a sign, and a huge number of balloons. But they are forced to stay in the workshop because a strong wind has picked up, and the balloons could fly away. The celebration is off the table! Only in the evening does the wind die down, and the sullen friends wander off toward their houses. By chance, the balloons do rise into the night sky, and the birds joyfully participate in this beautiful event. The opening truly takes place with great ceremony!
