Forest animals and the new year

On New Year's Eve, the forest beasts disturb the sleep of the hedgehogs who have fallen asleep with long-term plans. The hedgehog, who has come out of his den with the intention of solving everyone's problems, finds out that the animals are not fighting, but celebrating the New Year without a Christmas tree and a star. A little later, he returns to his den to wake up the neighboring hedgehog as well. What are the sleeping hedgehogs ready for?
