The Cannon Penis is SuperMarioGlitchy4's secret weapon that spawns from his crotch area.
- Bad Stars
- Bad Star's Back! 300k special
- Smexy Soccer (as Pingas Cannon)
- Can the Villager come out to play? (mentioned only)
- The Hangover
- Shooting things: SMG4 has used it to blast away various things including Peach, Toad and the Good Star, as well as Mario.
- The Cannon Penis comes from a joke from Smosh's Epic Vacation video, where they had a montage of random things, and one of them was a cannon penis.(The music played when SMG4 uses the cannon penis comes from that video as well.)
- Apparently, Mario and SMG4 occasionally refer to the cannon as "the thing", and Mario has told SMG4 to never use it.
- The picture used to represent it is actually a model of a cannon from Sonic Heroes and Sonic Generations.
