What&#39;s not love when a quartet of cousins visit their wacky uncle&#39;s private island, complete with horror-themed amusement park, on Halloween?<br /><br />The attraction is closed to the public for the night, too, so they have it all to themselves! No crowds! No lines! No waiting! A personal tour guide to take them around from attraction to attraction!<br /><br />But then, one by one, they start feeling not-so-well. Strange things seem to be happening. Is that a real werewolf lurking around in the shadows? Miss Penny&#39;s only wearing a witch outfit, isn&#39;t she?
