Six animated Hallowe'en adventures from Mona The Vampire, the modern heroine with a powerful imagination. In 'Witch Watch', Mona is trick or treating. But at the mysterious house that once belonged to the spooky Olden sisters, Mona's vampire intuition suspects her neighbours are not quite what they seem. 'The Hexed Mansion of Agatha Misty!' sees Agatha Misty move into a haunted house nearby, but Mona suspects that her creepy butler may be responsible for the strange goings-on. 'Ghouls Rule!' tells how Mona's treasured possession, the Book of the Slimy, falls into the wrong hands. In 'The Transylvanian Twist', Mona's vampire diary tells the story of a lovelorn lady vampire and a lonely-hearted werewolf - can Mona carry out Operation Dating Game before the full moon rises? In 'Creature From the Depths', an investigation reveals something unpleasant in the drains, but can Mona fix it before the plumber causes havoc? And finally in 'Mona and the Werewolf', all the clues suggest there's a werewolf in town, and Mona suspects foul play at school. But things get really bizarre when her plan to trap the suspect involves a chocolate bar wrapper.
