Microbombs are small Bob-ombs. They were originally manufactured by Punchinello after he figured out how to duplicate Bob-ombs.
The advantage to Microbombs is that they are very portable, and can be used in small areas. As with regular Bob-ombs, they can be used as weapons if you know how.
Microbombs are somewhat dangerous, and should not be handled unless you have an idea of what you are doing. Admiral Bobbery used Micro Bombs, or something similar, in Paper Mario: The Thousand Year Door.
