Olly was trying to think of a strategy but coming up blank. He really had nothing besides fly around randomly and hope a ball falls into the cauldron. Trying to catch the green ones had not worked for him yet, and he did not see him becoming any better at it in the foreseeable future. So option one it was. Olly flew over to where he spotted a bunch of the rubber balls and flew under them. He was hoping one or two would go in, and that he'd get lucky and get green ones, but no. Of course that's not what happened. Instead, a clump of five all fell into his cauldron.

Olly was not lucky enough that they would all five be green, of course. The problem was that he didn't know what color any of them were. The cauldron was strapped to his head so it wasn't like he could see inside it. Uh. He flew lower, down closer to the professor.

"Professor, if I didn't see what color the ball was how do I know if I got points?" Was there any simpler way to do it short of stopping completely, unstrapping the cauldron, and checking? That seemed like way too much work.
