Wand movement in an arch, left to right, a bit like a horseshoe. West practiced it a few times out of habit more than out of need, and then with his attention firmly on the frozen rabbit, he moved his wand again, "Lepus Caput!"

Sure enough the rabbit twitched but not of its own accord, instead it twitched and morphed and became a fluffy tophat. Which.... West wasn't entirely sure was his style but he'd give it a go he supposed? He picked it up and examined it, checking to see if there were any rabbit bits still attached. Like you didn't want the hat to poop on you for instance right? Right. But it was just a fluffy hat now, rabbit skin in fact. He put it on his head but there was a problem. Hmm.

It was just a bit too big, and therefore he couldn't quite set it at the jaunty angle that he preferred. Obviously West needed to give it another go. He put the hat down on his desk and then went to get another rabbit.
