King Pig

The King Pig is the king of all pigs. He usually comes in the final level of all themes. He is the biggest and strongest pig. In Mighty Hoax, he comes up with this brilliant idea to make a cardboard cutout of a pig. The birds don't notice until you finish Theme 4. Later, the birds defeat another cardboard cutout of the pig. The question is "How did the pig still make noise if he was a cardboard cutout?"
