Sweater Off Dead

This episode is great for several reasons. First, Cuphead's nightmare sequence shows that he seems to be throwing caution to the wind, but he's absolutely terrified of the Devil and doesn't want anyone else to worry, which is why he doesn't tell Elder Kettle that he lost at a satanic Skeeball game.

Second, Mugman may be timid and meek, but has incredible courage when facing the Devil. We're seeing this character reaching the limits of his patience and finally decide to take action.

Third, my small issue is that the world, at a first glance, seems too Christian. Randomly having the Devil as a character, let alone the main antagonist, is one thing, but the episode 'Ghosts Ain't Real' shows there's a church there. Until now, we had yet to see any other religion or anything secular. In this episode, we're introduced to Quadratus, who, like many of the show's other characters, is a character from the game. He's a mystical spirit in a rock pool who in the show gives sage advice on how to beat the Devil. Maybe I'm reading too much into things, but this is the point in the series where religion and secularism intersect.

I'd love to see this show expand on the theme of spirits, and do it in an entertaining way.

Also, any show that has a character blowing a raspberry at the Devil is doing something right.
