Hell's Bells (1929) on Netflix

The demons of hell play music for Satan, whose delight turns to wrath when an insubordinate refuses to become food for Cerberus.

Satan and the demons gather for a wild party. After the demons play music, Satan has them "milk" burning flames out of a dragon cow and he drinks them. He then feeds one of his little demons to his three-headed hound Cerberus. The other one runs away and eventually kicks Satan off a cliff where he is consumed by flames.

The demons of hell are a crazy, wicked bunch. A spider swings on his strand toward the viewer, doing his best to be menacing; but the anthropomorphic flames grab him and carry him down to an even deeper pit in Hell. Cerberus barks and scratches to the tune of "Jingle Bells." A dragon-like snake eats a bat who promptly pokes its wings through the beast and flies off. Meanwhile, little demons play "Funeral March of a Marionette" for Satan, who thoroughly enjoys it. It's time for Satan's meal, and two minions provide it by milking a demonic cow. Satan enjoys his flaming beverage, but his delight turns to wrath when one of the servers refuses to become food for Cerberus.
