FROBOZZ MAGIC ANTI-PIT BOMB
The grenade-sized
Frobozz Magic Anti-Pit Bomb is advertized as follows,
"Is your cavern infested with
bottomless pits? If so, this anti-pit
bomb is the answer to your prayers! Instructions: simply enter the
pitted room and throw the bomb. All pit-filling agents are harmless; no
protective gear is required!"
In
action, the bomb silently exploded into a growing cloud of
bottomless-pit-filling agents. The pits filled in from the bottom up.
