Shadow of a Skillit

S1 E6: Shadows are being stolen from all over Edge City! And everyone whose shadow is stolen loses his or her youth and starts to age rapidly. The Mask discovers that the shadow thief is Skillit, a 4,000-year-old "boy," something between Peter Pan and a vampire, who has known every previous owner of the mask. Skillit wants The Mask to come into Shadowland for fun and games, but The Mask refuses. The Mask insists that Skillit return the shadows--and their owners' youth.
