Pudgy World, the free-to-play game that allows players to customise their penguin avatar with unique digital traits, has been added to Amazon's marketplace. The traits, which are redeemable through the Pudgy Pass system, are available for purchase without the need for cryptocurrency wallets. The game, which launched earlier in the year, allows users to explore 12 unique "towns and is accessible from anywhere. However, there are also ongoing legal disputes with the owner of the Original Penguin apparel brand over trademark infringement.
