The Tweedle Bosses were removed because of their glitches and because they were not finished. The Tweedle Bosses took your gun with a magnet and shot you. There are two of them. You must have jumped to make them shoot each other. They were suppose to appear in the Jazz in Wonder Land levels. They were not included, because they weren't finished. If you add them in your level and you shoot where he was with ice, his shape appears!
