Ninja Potion of Magic Smoke
Used in CtFwS, this handy device allows you to escape from captivity. Also lets you be a totally badass ninja.
The Ninja Potion of Magic Smoke was invented by Sean McNinja (otherwise known as Dark Smoke Puncher) in order to fight dinosaurs in an alternate future, because his brother could not help but punch an astronaut. The relic fell in a time and space vortex and was found by the KGB while they were prowling a place that does not exist. Immediately seeing the use of such a brilliant invention, they immediately duplicated it for use.
