On this island every year celebrating the Frostivus. But this year, the evil magician has opened a portal from which gushed greevils and the celebration had to be suspended. Greevils stole all presents from the residents and dragged them to their dimension. Residents tried to catch greevils with many unusual traps, but they were smarter and managed to escape. And just now, while the portals are unstable, it is possible to return the Frostivus to inhabitants of the island, taking away gifts from greevils and returning them to the shopkeepers. But only one can be a hero in the battle for the Frostivus.
