Energy Hold
The Energy Hold is a location in Bowser's Body in Mario & Luigi: Bowser's Inside Story. This area is accessed to Mario and Luigi when they discover Durmite is one of the Star Sages. The two and Starlow come here, but are blocked by 4 Boo-like blocks.
Later on in the game, the area becomes more accessable when Bowser uses the Boo-ray Machine in the Tower of Yikk. The Boo blocks are gone, making it accessable to other rooms. Most of the rooms will require the Spin Jump, and the Mario bros also learn how to burrow underground, as well as collect Attack Pieces from blocks to learn a new attack.
After learning two new moves, the Bros. find Durmite, but entering a door, which can only be opened by a Star Panel. After a few more doors, they battle Durmite, who changes into Wisdurm during battle.
