I had this story idea that Millie gets the notion that Mr. Foxy might be "The Phantom" who's a mysterious trickster who's been pulling some rather painful practical jokes on the Athena's Engineering staff. Mr. Foxy decides to take refuge inside a boiler that's being descaled, and Millie can only glower and lunge at him through the empty burner port. Fortunately for Mr. Foxy, the REAL Phantom saves the day... Well, sort of.
