The climactic episodes see Cuphead finally lose his soul to the Devil. Mugman, devastated and alone, must team up with Elder Kettle and Ms. Chalice to literally storm Hell and get it back. This sequence is a love letter to the game—hand-drawn battle scenes, rolling dice platforms, and a final confrontation with the Devil that mirrors the game’s bullet-hell finale.

If you came for the game’s lore or emotional weight—prepare for whiplash. The show jettisons the original’s dark subtext (the brothers literally sold their souls) for lightweight mayhem. Characters like Grim Matchstick or Cagney Carnation appear as one-off jokes, not bosses. And the debt plot? Resolved in episode one. After that, the Devil just… wants revenge because he’s petty. It’s a choice that prioritizes comedy over continuity.

The series was first greenlit in July 2019 with a goal to expand the Cuphead universe through standalone, character-driven stories rather than a direct beat-for-beat adaptation of the game's boss-rush plot.

Special mention goes to as King Dice, who oozes silky menace in his few appearances.
