En route to Pittsburgh, Bugs Bunny makes a "wrong toin" and winds up in Transylvania, where accepts the hospitality of sinister vampire Count Bloodcount, who transforms into a bat whenever Bugs says "Abracadabra". Bugs never notices this metamorphosis because he always manages to reverse the spell by saying "Hokus Pokus!"--which returns the Count to human form before he is able to sink his fangs into the Bunny's neck. By the time this gag has been milked dry, Bugs begins experimenting with other magical words, each of which has a bizarre effect on the hapless Count--and on Bugs himself!
