A Robo-Bloog is essentially a Cyborg Bloog. It's a Bloog with the mind of ten super-computers and the body of...well, 10, super-computers. The Robo-Bloog can fire a huge ball of energy. If either Robo-Bloog or the energy ball hits Commander Keen, that's it. Unfortunately, every time the Robo-Bloog recharges his energy ball he adds one more shot to his attack. The more overcharged Robo-Bloog becomes, the more erratic his behavior is. It'll be hard to time your attacks! If you manage to Defeat Robo-Bloog, you'll get a Plasma Crystal.
