For those who still doubt the fact, Duckburg, Mouseton, and St. Canard MUST be in the same "cartoon universe." The appearance of "Starducks" in DARKWING DUCK #1 was not, as it turns out, the first time the ubiquitous coffee joint of that name has been mentioned in a Disney comic. Pride of (first) place goes to the SUPER GOOF story "Now Museum, Now You Don't" (Gemstone MICKEY MOUSE AND BLOTMAN #2, December 2006). Joe Torcivia gives the following line to Phineas Fawningfan, the would-be curator of the Super Goof Museum:
"What will we do? [Grumpy landlord] Picklepurse will throw us out and bring in another Starducks!"
The coffee in Mouseton is evidently every bit as potent as the brew in St. Canard. Super Goof calls Starducks coffee "thuh coffee so strong it puts feathers on a hairy chest," while Drake Mallard terms caffeine-fueled St. Canard "The City That Never Sleeps Soundly."
