Genderus Benderus is a spell that Morgan made up when he was bored and wanted his favourite kind of fun - Gender Bending Fun. It can simply be used by pointing at the desired target, and screaming 'GENDERUS BENDERUS!' at the top of your lungs. If done correctly, then the victim should have turned into the opposite sex. If done wrong... I'll leave you to clean up.
