Tallest Mountain

The Tallest Mountain is a mountain far north of Club Penguin. It can only be accessed by the first Secret Agent Mission, and this is the only proof of its existence at all. Aunt Arctic's green and purple puffles once hid up there. In the mission, you can only access it using G's grappling hook in Mission 1, The Case of The Missing Puffles.

However, a puffle (or penguin) could perhaps use a propeller cap to ascend up there.
