"If you insist on behaving like a rude, disobedient pig you shall become one" Elspeth warned "From now on every time you complain, defy me or fail to carry out your instructions successfully you will transform a little more into a hog. Do you understand?"
"But that isn't fair!" James blurted out without thinking.
"That sounded like a complaint to me" Elspeth folded her arms and shook her head in dissaproval.
Sure enough, James soon felt a tingling sensation just above his buttocks and turned his head in it's direction just in time to witness a small, pink, curly tail sprout into existence.
"What the..." he began, but managed to stop himself before making the situation any worse.
"You learn quickly" Elspeth smiled down victoriously at the terrified naked man "You'd best keep it up. In a few days I'll either have an obedient human servant or a prize pig to sell at market. Either works for me"
James stared at the witch in disbelief but said nothing.
"Ok, now you have a proper incentive to do as you are told, what should I have you do?" Elspeth pondered, stroking her chin.
