Avenging Spotty 1331 / Eliminate Buffalo Bandits.

[Mr. McPhy], convinced that the Buffalo Bandits wronged Spotty, asked me to take care of them. I should eliminate 3 yellow-haired, 3 black-haired, and 3 white-haired Buffalo Bandits.
Let's eliminate 3 bandits each guy with [yellow mane], [black mane],
and [white mane].
