Reuses several plot elements from the black-and-white Fleischer Popeye short, "Ghosks is the Bunk."
The opening scene of a ghostly Jack o' lantern, and Bluto's appearing as a headless pumpkin head, might be a nod to Disney's animated feature The Legend of Sleepy Hollow, released in 1949.
Popeye and Bluto break the fourth wall in a very unusual way here.
Most animation studios had spooky themed cartoons at the time.
The odd-looking object next to Olive's sofa (and Bluto) is the once-common stand-up ashtray.
