Darkwing is sent by S.H.U.S.H. to investigate cases of living Quackerware, believing Herb Muddlefoot to be the culprit. Drake investigates by joining in on Herb's Quackerware sales route, all while Gryzlikoff tries to investigate on his own.
This episode contains examples of the following tropes:
- Absentee Actor: Gosalyn doesn't appear in the episode.
- Animate Inanimate Objects: Weasel Lowman somehow built a machine that can transform Quackerware into his minions.
- Berserk Button: Herb, of all characters, is shown to have one when facing off against evil salesman Weasel Loman.Weasel: "Quackerware's a tenth rate product! It took me to realize its true potential!"
Herb: "You can disgrace yourself, and you can disgrace me, Weasel. But when you start messin' with Quackerware, that's it for old Herb Muddlefoot! Come on!"
- ...But He Sounds Handsome: In the last scene, Darkwing doesn't miss the chance to call Drake Mallard "good-looking" when talking to Herb.
- Pokémon Speak: The only thing the living Quackerware can say is "Sir!", likely referring to their master, Weasel Lowman.
- Pop-Culture Pun Episode Title: A reference of The Merchant of Venice.
- Serious Business: Herb really takes his Quackerware selling serious, so much that he's ticked off when he finds out that Weasel has been turning it into living robotic thieves.
- Shout-Out: The villain is named Weasel Loman. He also has a Richard Nixon-like voice.
