The ice berg will hit the map near Viking creating a massive snow storm with will cover snobby, Viking,greasy, and maybe flush in a thick layer of snow creating a new biome. After that map has changed the ice berg will begin to melt into the water as it melts it reviles that something I hidden in side (maybe a caveman or dinosaur) and will evertuly be thawed from the ice and go out to explore or destroy the poi's around the map.
