Eureeka's Castle

Wide Awake at Eureeka's Castle (1x1)

Air date: Sep 04, 1989

The main plot is Magellen (a dragon who has a tail with a mind of its own) and Batly (a near-sighted bat; my personal favorite), challenge each other to a contest to see who can stay awake the longest. Eureeka later joins the contest, and they all share stories of when they couldn't go to sleep other nights.
