Boo-ray Machine

The Boo-ray Machine is a machine in Mario & Luigi: Bowser's Inside Story that Yikk built before he passed away. Yikk explained that the light makes the insides of one's body visible, and that it shows Boo transparency waves, giving off light and other special properties. Once Bowser activates the machine, Mario and Luigi, who are inside of Bowser to pursue Wisdurm, are able to access more of the Energy Hold, where they follow after Durmite. If Bowser keeps the Boo-ray Machine activated, Mario and Luigi may see hidden blocks somewhere. If Bowser deactivates it, several Boo-like blocks may appear as platforms.
