"Which means I gotta change you more." The barkeep pulled out a glowing stone and glared at Mika. "When I say draft horse, I mean draft horse."
"But..." Mika's protest was cut off as he felt his body shift again. This time he got noticeably shorter, and was embarrassed when he wet himself. It was hard to think, and he stared at the mules in confusion. Then he looked down at himself. Mike was now a scrawny boy of 14 or 15, filthy and naked. He was well endowed at least, much better than he had been as an adult. But his teeth were still crooked and scummy and he had the same tangled mop of matted red hair.
"You live out here now, boy. Little better than the animals you take care of. Or create." The barkeep grinned. "You might even come to like this."
Mika went into the stall and enjoyed petting the mules, which rubbed against him. He felt very content with the animals, so much so that he did not notice his master leaving. The former wizard was vaguely aware that he had been changed, but it was easy to let the dull stableboy mindset take over. He mucked the stalls and groomed the mules, then went to sleep in the corner of their stall.
