Three friends – Robot, Chicken and Worm decide to open a birdhouse city. For the opening, everything is ready: the birdhouses are already waiting for their residents on a beautiful meadow. Friends decide to make the opening very solemn – with music, a sign and a huge number of inflatable balloons. But they have to sit in the workshop, as a strong wind has risen and the balloons can fly away. The celebration will not work out! Only in the evening the wind ends, and gloomy friends walk towards their houses. By chance, the balloons do fly up into the night sky, and the birds happily take part in this beautiful action. The opening is really very solemn!
