How can we turn a hireling into a horse?
A coworker asked me today a game question. They're playing 5E DnD, which I'm not yet intimately familiar with. They have a hireling that they'd really like to turn (temporarily) into a horse. Bonus points if they can somehow keep the horse's head human (not centaur-like. Just the head.). They're currently level 3, and are seeking the best way to do this at an early level.
The closest I could get based on my knowledge would be either have the hireling take a level of druid (may not be an option), get to 7th level so their wizard can cast Polymorph, or find a magical item that lets them use polymorph. I also suggested that they could just buy a horse, but that's apparently not something they're interested in.
Is there some other way they might be able to do this? I imagine it would rely on DM fiat, but I'd be interested to see what rules the site can bring to bear on this.
