On a single, normal night, a pony is heading home from a party. Well, he never arrives home and worry starts to spread. The close ones of the missing one get worried, of course, and after some discussing with the police, a search party is arranged.
But the things the party finds pretty much turn the life of the residents of the whole town upside-down.
And after all, the only thing this thing wants is a little fun. And maybe some chaos if any can be found.
