DEMON IN THE MATTRESS
In a wonderful spoof of The Exorcist, the new mattress that Muriel orders comes complete with a demon that proceeds to possess her! It's up to Courage and Eustace to try and exorcise the demon from Muriel before it's too late. Eustace fails at the attempted exorcism, but Courage is successful...unfortunately, the demon leaves Muriel and takes control of Eustace in the end!
Pea soup, anyone?
