One cold, wet night three lost teens – Skip, April and Augie plus their dog Elmo – stumbled upon a spooky old house hoping to get warm. The dusty clock showed the wrong time, so these helpful kids reset the clock hands. A gong rang out, followed by a voice: It’s the Spirit of 1776, even, at your service! Much to their surprise was the friendly ghost Mudsy (voiced by legendary actor Daws Butler) and his mischievous ghost cat Boo. Antics abound when this motley group hits the road, cracking cases and thwarting crooks, pirates, ghosts and all kinds of strange characters in this rib-tickling animated Hanna-Barbera series. It’s no mystery that Mudsy, Boo and the gang are fun for everyone in these seventeen episodes!
