Pins exist in the form of an icon that appears on the top-left corner of player cards.
Pins are obtainable on the island by finding their hidden location. Generally, every couple weeks or so, a new pin (or multiple pins) will be hidden around the island. To obtain that pin, one must find where it is located and either click on or waddle over to the pin to collect it. Sometimes a pin will require you to do a bit more work to uncover, but we will leave that up to you penguins to discover.
Pins may also be distributed as a reward for contributing to donating to a charitable cause during certain events.
Pins also exist in the form of flags. Flag pins are made available in each release of the Penguin Style catalog. They are located toward the back of each respective Penguin Style catalog and are purchasable for 20 coins each.
