Steam-O-Matic

The Steam-O-Matic is a steam-producing device owned by the famous wrestler Sgt. Slaughter (real name: Robert Rudolph Remus).

In The Super Mario Bros. Super Show! live-action segment "All Steamed Up", Sgt. Slaughter sends the Steam-O-Matic to Mario and Luigi so that they can repair an unspecified problem with it.

After the Steam-O-Matic is repaired, Mario, wanting to make sure it is fully functional, goes inside of it, only to become stuck; to make matters worse, Luigi and the recently arrived Sgt. Slaughter turn the Steam-O-Matic on to full power.

Eventually, after a long while of pounding on the Steam-O-Matic door, Mario is able to break-out of it, though he is shrunken in size due to extreme steam exposure.
