The rumor would have started once CP released the Miners Helmet. Penguins would have simply drilled at the Iceberg and they had assumed that it would tip. Eventually this rumor spread to blogs and on other social media. CP started making comics, wallpapers and postcards about it. Eventually, a painting of a tipped iceberg was found in the renovated Lodge Attic.There is also a stamp called 'Berg Drill'. Eventually, this rumor came true.
