Comet in moominland is about them learning about a comet heading towards earth that they believe is going to kill them all.

It is fantastically bleak, with the sea drying up, and that doomsday prophet reminding them that everything will be destroyed. Then the comet somehow misses, which they react to with a sort of dreamy, "oh. Right." and even the cake moominmom bakes to celebrate that they're not all dead after all, gets ruined because that damn doomsday prophet sits on it.

Damn. Don’t look up, Moomins!
