Summary
Warren Patterson was just a kid like you, or he was until he found evil Gorghool's magic jewel. Then he tricked him, and he read a spell, now every time he sneezes, he becomes a Monster by Mistake. However, his sister Tracy tries the spellbook to try and get him back to his former width and height, however, as always, she never gets it right, and so Warren develops a lust... A lust for the ghost that lives up in the attic. But he can rest easy knowing that Johnny always has a helping hand to lend.
