Even better than that little tidbit: One of the bosses in the game is named Sheep Man!
He certainly looks like a sheep, doesn't he? I'm not sure he fights like one, though. (Of course, I'm not exactly sure how a robotic sheep should fight.) According to the article, Sheep Man turns himself into four clouds that hover over our intrepid hero (I've always wanted to use that phrase in an article) and attack him from above.
The player's prize for sending Sheep Man back to his pen where he belongs? The oh-so-awesome-sounding "Thunder Wool" weapon which, according to Nintendo Power, "floats up at an angle before releasing an electrical burst."
Many more morsels of information can be found in the first two pages of the feature, which can be found here.
