It’s a Slice of Life show that resets everything after each episode where either Eustace is killed, the farmhouse is destroyed, Courage or Eustace is turned into something or the Bagges become permanently changed. There’s no full fledged story, just a cartoony segment where the impossible happens and it’s all undone afterwards.
Yet, Straight Outta Nowhere, a.k.a The Scooby Doo crossover film implies that the whole series actually DID happen as a story, as Courage is seen morphing into many different forms as a means of telling Scooby and Shaggy the story of his life. Plus there’s also many Easter Eggs of past villains and monsters from the show. W hich means the whole show actually IS interconnected.
Cartoon logic aside, how does everything return to normal in Nowhere all the time?!?! How is the farmhouse still standing and how is Eustace still alive?!
