A hedgehog, a hare and an owl are four friends who have met at the edge of a wood to explore an old astronomer´s station. Everything is new for them, they have never seen anything like that and when they see a rocket taking off they are dumbfounded. None of them knows what it could be so they devise silly ideas one after another. They might have been discussing it up to now if it hasn´t been for a clever mouse who has explained everything. The mouse has spent all his life with scientists at the station so he knows a lot about the space.
