Puffle Roundup is located at the Pet Shop on Club Penguin. In this game you need to guide Puffles into the pen.
However, you have to do it under a certain time.
At the top it’ll say how many you successfully caught and how many excaped.
The more you capture the more coins you will get. Doing it in a smaller amount of time also results in more coins.
As you can see, after only one round I got 55 coins! It’s a fast paced and easy game.
