The Carabiner Pin is a pin in Club Penguin. It was free and was available to all penguins at the Lighthouse. It was probably released because a carabiner clips you on to a hold while climb a cliff when you climb a mountain, for the Mountain Expedition. It was hidden in almost the exact spot as the Fireworks Pin. This is a pin that isn't huge, unlike previous pins which were relatively about the size or bigger than penguins. It is Club Penguin's 131st pin.
This pin was active from August 12, 2010 to August 26, 2010.
It makes an appearance on the August 2010 page of the 2009-2010 Yearbook when the cloud in the upper right corner is clicked on.
