I'd forgotten about this comic until I came across a site dedicated to it – it was a truly terrifying horror comic for small girls that ran for a couple of years at the end of the Seventies. The best thing about it, apart from the evil glamour of Misty herself, were the merciless moral lessons it imparted. Yes, you love your pony but is it at the price of your soul?:

And, most importantly:

Never mock a monkey.
