It is hard to tell who they are because there are no colors. They look like snowman-monsters! I can tell because the noses look like carrots! I have NEVER seen those guys before. They look super evil! I think they probably came from Herbert. Maybe they came from Sensei's arch enemy! I don't know if Sensei has an arch enemy. Maybe they came from his evil brother! I don't know if Sensei even has a brother! THIS IS GOING TO BE EPIC!!!!
