Once there was a man named Ronald McDonald. He died, but came back to life. When he died, half of him was torn away into a ghost. This ghost was not Inky, and has nothing to do with Inky. Inky was some loser who died in a blowtorch accident. He became a ghost and started craving Pac-Man meat.
Inky is known for his ability to Blow Stuff Up. All he needs is enough Dynamite! Inky is very good with explosives, but he is afraid of them, so that's rather pathetic.
