M-beply is a robot given to people when they start to traverse through the world of Fnauns. It has a small container in its center that contain the energy (f-fuel) which tames Fnauns, but this one is very condensed and can tame a Fnaun immidiatly, not having to wear the wild Fnaun down. The condensed f-fuel shoots out of the red antenna. The condensed f-fuel is a very dangerous force in the wroge hands, and is kept safe in a top-secret lab, only extracted in small portions.
The genius who invented M-beply's was longing for an avocado, which shows through in the design. Once the condensed f-fuel is transfered to tame a wild Fnaun, the M-beply is useless, though some keep it as a memento. Though it seems like there is barely space where the condensed f-fuel is, there is much space, and the shell can be used to hold Fnaun and/or items like a backpack
