This is the only episode of season 2 not to have a Chase song.
Second episode set in a specifically stated location, the first being Mystery Mask Mix-Up (1970) which is recognizably set in San Francisco.
Second time the gang encounter a witch doctor, the first being the Indian Witch Doctor in Decoy for a Dognapper (1969).
One of the few times in the original Scooby Doo Series that we see Velma out of her signature orange turtle neck, burnt color skirt and orange socks and shoes! She is in a native grass hula skirt, tube top, bare foot and a lai!
