Notice at the end of my video after you got revenge on moneybag man at 3:00 mark:
What the moneybag man said after the 3 minute mark was a quotation by dick dastardly from "Dastardly & Mutley in their flying machines" and "Wacky Races."
**But for the achievement, you must get revenge on moneybag man.** Will become available after beating the sorceress for the first time.
