Sophie and Quintion recruit their favorite cartoon heroes and consult a team of architects to construct a very large castle next to the WilliamWill Manor to serve as a clubhouse for the good team. Christened the Cartoon Castle, it acts similarly to a hotel with separate rooms such as a kitchen, a ballroom, an arcade, a swimming pool, etc.
Meanwhile, the antagonists to the cartoon heroes, lead by Andy Panda create a rival castle called the Depress Fortress. Their goal is to try and wreck the Cartoon Castle and/or conquer it, but their attempts often backfire.
In each episode, it is a slice of life themed experience in and out of the Cartoon Castle with our heroes while trying to defeat the villains and destroy the Depress Fortress for good.
