I hate to burst all your bubbles, but Arctic Macrob begins with the letter A. If they're going to sort the entries alphabetically it would naturally be up near the top.

And Arctic Macrob has "pseudo" bosses, the things that spawn the various enemies you run into. You merely need to find enough stuff to grow your 'anti-boss' and eliminate the level's boss. Imp5 was just a bit creative with the word "boss" and the common interpretation of it.

It doesn't matter what you all think because the judges word is final. Therefore this arguement is a moot point, why bother continuing?
