La llegada del cometa

The Moomins live a quiet and peaceful life in the valley until one day all the colors disappear. The trees, the flowers... even the multi-colored bridge Moomin Dad just built have turned gray. Moomin decides to investigate what happened and, together with his friend Sniff, he embarks down the river in search of a mysterious observatory to find out if the valley is really threatened by a cataclysm. During their journey they will encounter dangerous creatures, such as a huge saurian, a condor and a ferocious bush, and they will make new friends who will join their expedition. The very diverse group will have to unite all their ingenuity to take cover from the fearsome comet that is approaching the Valley of the Moomins.
