Forrest was fairly sure he got the spell alright, so he grabbed Robbie again. He looked around for a moment to watch people, because he still didn't want to do this. But it was Professor Bellaire--currently, she wasn't bella at all FYI--and he wanted to help Hufflepuff win the cup again so... Robbie was to be sacrificed only for a while. As soon as his hat was graded, Forrest would return him back to his bouncy rabbit self.

He took a deep breath, readied his wand, and aimed at Robbie's little tail. He figured if he miscast the spell, the least useful part was his tail. He took another deep breath, drew his wand from left-to-right in an arch as was shown by the professor, and was saying in the process "Lepus Caput."

Did it work?
