Frosted Glacier is the snow themed fifth world of New Super Mario Bros. U. It is similar to World 5 from New Super Mario Bros. , but unlike that world, this world is at night instead of day. It is to the northeast of Acorn Plains and Layer-Cake Desert , north of Sparkling Waters and Soda Jungle , northwest of Rock Candy Mines and west of Meringue Clouds and Peach's Castle . Wendy Orlean Koopa and another Boom Boom are here.
