S2·E20 Mr. Wubby

Voltar is unable to sleep when his sleepy-time blanket, Mister Wubby, is accidentally sold by Red Menace at a yard sale. Things go even worse when they discover that the new owner is none other than Metrotown's very own nighttime defender Nightshade. Now it's a race against time to get Voltar's precious Wubby back, because no Wubby and no sleep make Voltar really cranky.
