The second dungeon in the Enveloping Garden. Rose Pikmin are discovered here on Level 5. It is also the second Tree Climb in the game. All of the levels are randomly generated except for level five and seven. There is also a boss at the end. There are very few enemies in this dungeon but there is the introduction of hot tar hazards, hence the name of the place. It is required to beat the Beastly Burrow before going over there and challenging this dungeon due to the mossy gates that require the Plant Paralyzer ability to destroy. The terrain is mostly black earth but changes to light earth as the player ascends to the higher levels.
