Everyone's a Member
Every penguin is a member here. There is nothing to buy.
Membership is free
You do not need to pay for anything on the island. There are no subscriptions, no membership cards and no shop that takes real money.
When the game says something is for members, that means you.
How you get things
Clothes, furniture, igloos and puffles are bought with coins. You earn coins by playing the games on the island.
Some things are earned by doing them: stamps for challenges, belts for winning at Card-Jitsu, pins for finding them.
Nobody can sell or give you coins or items, not even staff. Anyone who offers is trying to trick you.
