Autobomb

Autobombs are Shy Guys that ride on cannons with wheels. Shooting fireballs, they plauge the land of Sub-Con, they work for Wart. On the side of their cannons is the letter "M". This probably stands for Wart's japanese name, Mamu, and was unchanged for the American version. When Mario or one of his friends threw the Shy Guy rider off, he or she could ride on the cannon. This was required on some levels.
