The Freezing Inferno is a cave in Pikmin 4. It is found in Hero's Hideaway, on the counter in the kitchen. The cave is in a burner on a stove, so you can only get in if you have the Scorch Guard. This also means that only Red Pikmin can get in. When the cave is completed, you exit on the other side on a wall, making it possible to enter the cave non-red Pikmin, and that the Ice Pikmin onion is available.
