Can Marvo the Magician's awful assistant be taught new tricks by Hocus Pocus Hound? Doris is the world's worst magician's assistant - she muddles up the magic cards, mislays the magic wand and swiggs three extra-large milkshakes just before she's about to get sawn in half! Her boss Marvo gives her the sack. Because Marvo is mean he decides to employ a stray dog as his new assistant, as he won't have to pay any wages. Despite a slight wind problem, Hocus Pocus Hound turns out to be a great magician's assistant - he juggles, balances boiled eggs on his tail and never wriggles when being sawn in half. Marvo's act takes off, but he gets really greedy. Doris and HPH have one last trick up their sleeves to get their own back...
