The other girl from their boat seemed to be doing fine, so Indigo focused his attention on the hinkypunk that he'd just solidified. They were weird little creatures. He half wondered what would happen if he just kicked it. That seemed like it would have pretty much the same effect as the knockback jinx, wouldn't it? But no, that wasn't what they were supposed to be doing. "Flipendo." He cast the spell the direction of the hinkypunk and that took care of it. This was pretty easy. Hinkypunks weren't that hard to defeat. But to be fair they were in the classroom and prepared for this, so things might be different if the situation was more organic.
