It was an operation to capture Herbert. When you completed the final System Defender level, you would find out that Herbert is hiding out at the Toughest Mountain, the site of the Great Snow Race. At the Toughest Mountain, you would have to put him into "hibernation", but first you had to get through a Laser Maze. Once you had gotten through the Laser Maze, you had to use the Expedition Key Pin to unlock the door, taking you to the Classified Area. You then had to throw snowballs at the control panes to dismantle the alarms. Then, using the parts that G teleported into the Classified Area, you had to build an air-conditioned box around Herbert and Klutzy. Once you had defeated him, you earn the AC 3000 Pin and 3 medals. However, Klutzy escaped.
