Autobomb

Autobombs are large, gray, wheeled cannons which launch projectiles and can be ridden on.

In Super Mario Bros. 2, Autobombs were utilized by Shy Guys as a means of transportation and offense. If the player could dodge the projectiles shot by an Autobomb and threw the machines Shy Guy pilot off it, they could ride it. In some levels of Super Mario Bros. 2, riding an Autobomb was mandatory in order to cross large, spike-filled gaps.

[edit] Appearances in Other Media In The Super Mario Bros. Super Show!, Autobombs, never reffered to by name, only made an one appearance, in the episode "Koopenstein"; an Autobomb first appeared in the episode when Mario, Luigi and Princess Peach are captured by Mouser and a group of Shy Guys. Later, Toad, when surrounded by Shy Guys, manages to light the fuse of a nearby Autobomb using a Piranha Plant, causing it to blast the surrounding Shy Guys, creating a distraction that allowed Toad to escape.

Trivia
According to the manual of Super Mario Bros. 2, Autobombs are also known by the alternate name of "Bad Dream Machines". The "M" emblazoned on the side of every Autobomb may stand for Mamu, the Japanese name of Wart, the main villain of Super Mario Bros. 2.
