Tower of Yikk

Ibikki Tower is a location from Mario & Luigi: Bowser's Inside Story. It is a large, mechanical tower built by the late Ibikki. It is capable of autonomous movement.

Ibikki Tower is first discovered by Bowser while he is searching for the first Star Vaccine. On his way to Ekubon's Forest to confront Imounu, (who is not there, unbeknown to Bowser,) he passes a propeller protruding from the surface of Zutsuda Lake. The Koopa King takes advantage of an allergy to a nearby plant, activating the propeller with a sneeze. This causes the submerged tower to come to life, escaping from the lake and crushing Bowser beneath a mechanical leg. Traveling to an adrenal gland, the Mario Bros. activate Bowser's ability to grow to match the size of the tower. Bowser's strength is able to deactivate the tower permanently, gaining him access.

Inside the tower is a Save Block and a Shop Block. A short hallway and an elevator ride lead to what appears to be some sort of study. Here, the door locks behind Bowser. The spirit of Ibikki appears and shows Bowser the Boo Light Machine, which allows the Mario Bros. to pursue Imounu.
