The little dragon Coconut and his friends, Matilda and Oscar, travel through time and go back to Prehistory. They want to learn about the first dragons. But Prehistory is a dangerous era: Matilda almost falls into the trap of a prehistoric hunter and a huge bear threatens to eat the three friends... And then there are the two dragon eggs that Coconut frees from the glacier's ice by breathing a little fire from his mouth... Do they perhaps contain little dragons?
