Instructions
Read the Club Penguin newspaper to know when a new pin will be appearing. You can also read the "What's New" section on the homepage.
Log on to Club Penguin when the pin is due to be available.
Search throughout Club Penguin. The pins' locations are normally not announced, and they're often hidden in strange locations. Sometimes, other characters will gather where they've found a pin, so a crowd of penguins could be a clue.
Walk over to the pin once you find it, then click on "Yes" when asked if you want it.
