To get the Jet Pack on Club Penguin you must be a member! First go to the Hot air Balloon ride!
Once you get on the Balloon Ride you will Travel to the New Room. Club Penguins Tallest Mountain!! Once you arrive exit the Ride and at the Tallest mountain there will be a Box where you can pick up Jet Packs!
Also if you go to the Top of the Mountain you will notice that the Invention Holding up Club Penguin is the Island Lifter 3000! Thats it for now!
