The Energy Hold is a location in Bowser's body that appears in the game Mario & Luigi: Bowser's Inside Story. It is one of five major locations that can be explored in Bowser's body including the Trash Pit, the Pump Works, the Flab Zone, and the Airway. The Energy Hold is also the largest area in Bowser's body.
Mario and Luigi head to the Energy Hold after learning that one of the sages for the Star Cures, Durmite, is located here. Mario and Luigi must use a teamwork from Bowser who is in the Tower of Yikk to activate and deactivate the Boo-ray Machine in order to access some areas. After finding and defeating Durmite, also known as Wisdurm, they earn the first Star Cure and leave the Energy Hold.
