Smart Bomb (Nintendo Comics System)

Smart Bombs are red colored explosives created by the Koopa Troop that only appear in the Nintendo Comics System issue, "Duh Stoopid Bomb!".

The Smart Bombs act as a counterpart to the titular Stupid Bombs, likely as a countermeasure or contingency in the event the Stupid Bombs backfired on them. They release an intelligence-raising gas when detonated.

Description
Shortly after a Snifit reported to King Koopa that several of his Shy Guys had set off Stupid Bombs and rendered themselves dunces, the King shows him a cache of Smart Bombs, explaining their purpose and his plan to counteract the Stupid Bombs affecting his soldiers. The curious Snifit grabs a Smart Bomb, which goes off in his hands, and breathes in the fumes; he becomes superintelligent, and sends King Koopa down to Fryguy Kindergarten before trying in vain to re-train the Shy Guy soldiers.
