The Machine Planet Mekkai (originally Mecheye) is the mechanical star of the nearby galaxy in Milky Way Wishes. It is the sixth planet, following Cavius and preceding Halfmoon. It is extremely technologically advanced and well built. The entire star looks hand-made. The entire metropolis is large enough to be viewed from outer space. A lot of the planet features numerous hazards, such as the first room having Gordos and electrical hazards, and the second featuring more Gordos and strong winds. The last room features an elevator which leads to all the mid-bosses, similar to Cavius, except only two are necessary to complete Milky Way Wishes.
Due to the way copying abilities works in Milky Way Wishes, abilities can only be obtained from enemies using the Copy ability provided by the Copy Copy Essence Deluxe (though there are a few exceptions).
- Yo-Yo: In the windy area in the third room, there is a door on the ceiling. Enter the door. Go down the elevator to the bottom. Enter the next door
- Plasma: In the room full of Mid-bosses, go up the elevator to the very top and go to the left. After defeating Iron Mam, the Plasma Copy Essence Deluxe will appear.
