The Mini-Mini Device is a plot object in Bomberman Max 2.
Description[]
This device was built by Mujoe in an attempt to control the world. The device is remote-controlled and is able to shrink people. It was placed in the Bomber Base with the help of the Hige Hige Bandits. They lured Bomberman and Max, and when they were both close to the device, Mujoe remote-activated the device and shrunk both of them.
The device itself is powered by 5 lights, each light is connected/represents one of the 5 worlds, with each boss guarding a switch that controls the world's light. In the end they managed to disable the 5 lights and were able to deactivate the device, and get back to their normal size as a result. It is not clear what happened to the device after that.
