Winter has come to Redstone Junior High once again, and with it comes holiday celebrations, snowball combat practice, and loads of outdoor fun. But even though the threat of Smite and his henchmen has passed, a new, sinister force lurks in the dark hallways of the school. Strange blocks begin to appear in random places throughout the school and students have been hearing eerie sounds coming from its abandoned corridors. Pixel, Sky, and Uma team up to figure out what's tormenting their school and why.
