After partying all night, Bunnicula must make it back home and avoid the sunlight or he'll turn to ash. Bunnicula tries various ways to block the sunlight such as mailing himself back to Mina, walking in a solar eclipse, and covering himself in clothes, but nothing works. Finally, Bunnicula makes it back home, but Harold accidentally lets the sun in and Bunnicula turns to ash. Chester and Harold try to fix him, but they fail. Bunnicula then sees a full moonbeam, which revives him.
