Pal’s name is the only one on the credits, so it’s tough to say who worked on this. Film Composers in America by Clifford McCarty reveals the score was done by Eddison von Ottenfeld, who was using the name William Eddison. Variety says little about the short, other than this in its August 28, 1942 edition:
George Pal closes his studio today to provide annual 10 day vacation for all employees. Producer just completed the Puppetoon short, 'Jasper and the Haunted House' for Paramount release. Pal heads for his cabin in the high Sierras.The short’s national release was on October 23rd. It was the first Puppetoon of the 1942-43 season.
