Jasper and the Haunted House is a 1942 American animated short film in the Madcap Model series by George Pal.
[1] It is an early entry that features the popular yet controversial Paramount Puppetoons characters Jasper and his friend/nemesis Professor Scarecrow and Blackbird.
Frightened, Professor Scarecrow and Blackbird hide in the piano with Jasper after the pie is eaten and the invisible ghost tosses back the pan ("There ya' are, boys.
The three characters whisper that they cannot see him, and there's a swing boogie-woogie piece played[4] (possibly influenced by Thanks for the Boogie Ride) and every inanimate object begins to dance, from the grandfather clock to the bookshelf to the pie pan.
The ghost's vigorous playing sends the trio out of the piano, out through the roof of the haunted house, and they hit a billboard.
Jasper drops the pan onto the ground revealing the Paramount Pictures print logo of the time on it.
& M. TV Corporation and the Paramount pie pan was cut out and was replaced by the same "The End" title used in Little Lulu films.
