Iggy's Swinging-Chains Castle
From the Super Mario Wiki
Iggy's Swinging-Chains Castle, or Soda Jungle-Castle, is the Castle level of Soda Jungle in New Super Luigi U. It is unlocked by completing Sumo Bro Bridge or Wiggler Floodlands, and its own completion will unlock Mount Fuzzy.
At the beginning of the level, Luigi must swing on a chain above lava waves. A moving platform with two ? Blocks above it is found, followed by three more chains. Three more moving platforms are found, two of which have Dry Bones on them. Three Brick Blocks float above the middle platform. More chains are found, along with a Green Ring. Some more chains are found, along with the boss door and a Dry Bones. Luigi must battle Iggy Koopa, who fights as he did in the game's predecessor; the only difference is that lava waves are now included in the battle.
