When you finish that, play Electric Shocktopus! Use the power of electrostatic forces to help our hero, the titular Shocktopus, take revenge against the Magnetic Yeti. It’s a dangerous world, but our little Cephalopod has a trick up one of his eight sleeves: he can change his electric charge at will.
