Even if I didn’t know Herbert is planning to attack System Defender soon in a seventh level, if you pay attention to one small detail on Club Penguin it’s already obvious. Before the AC 3000 you can see Klutzy.
Then once you assemble the box he escapes out of the tube through the pipe and goes off to who knows where!
Obviously Klutzy is somehow going to save the day. Maybe he will use his claws to snap the yellow wire that is powering the Mini AC 3000?
