* FridgeBrilliance: Von Goosewing's continual attempts to kill Duckula make sense when you consider he's the first instance of a vegetarian vampire in centuries of Duckula revivals, and previous incarnations were noted for their cleverness. Given the past Duckulas, Von Goosewing's is simply WrongGenreSavvy, if anything.
** In addition the villainous Duckula used in ''DangerMouse'' may be one of said incarnations before meeting his end (and thus setting up for Igor's botched ritual).
* Why does the ketchup, a product usually served on ''meat'', turn Duckula into a vegetarian, rather than just making him a meat eater instead of a blood drinker? Ostensibly, because it was made from Tomatoes. But shouldn't that have given Duckula a craving for ''fruits'' instead? Tomatoes aren't vegetables, after all.
