Dracula, Frankenstein and the Invisible Man meet at a twenty-four hour pancake house to figure out why no one- including their cheerful waitress- seems to be scared of monsters anymore. The Sand Witch, the bumbling terror of the beach, wishes to join the ranks of these legends of horror. As the Sand Witch shows off her not-so-menacing moves on the seashore, she is pranked by a child. The child turns out to be a victim of the Sand Witch's sandcastle-smashing shenanigans. With the tables turned, the Sand Witch is surprised to learn that scaring someone is not all fun and games. It can cause sadness. A late invitee to the monster meeting arrives. He is a doctor who strongly believes that there is good in everyone. He encourages the feuding witch and child to put aside their differences. As they reluctantly consider his proposition, the sensitive scientist, by the name of Dr. Jekyll, turns into Mr. Hyde. The two ban together to stop this force of beastly fury.
