"Fungus Amongus" is the twenty-first episode of Darkwing Duck, and the fourth episode to air on ABC.
A series of supernatural pizza topping thefts leads DW to the place that is home to St. Canard's mushroom production - Macawber Mansion. However, instead of keeping his thoughts on the case, he ends up falling for Morgana Macawber, the chair of the company. Can he crack this mysterious case, or has the hero been bitten too hard by the love bug?
- This is Morgana's first appearance in both production and airing order. However, due to this episode having premiered on ABC, this puts it after her later appearances in the syndicated episodes in the order used by the DVD sets.
