<p>To mark this creepy day, Toby has chosen to tell you about a few of the most bloodthirsty ancient mythical creatures from different cultures and countries, from Scotland's Kelpie (clue: they're not cute or like your fluffy unicorn) to Ireland's Banshee (yes: she is screaming, and so will you be if you go too near her).</p> <p>Which one do you think is most frightening?</p> <p><br></p>
