What is the code for a yellow puffle and hat on club penguin?

In Club Penguin, to get a yellow puffle, you could typically adopt one from the Puffle Hotel or the Puffle Hotel's pet shop. For the yellow puffle hat, you would usually need to visit the Puffle Hotel or complete specific tasks or missions related to puffles. However, since Club Penguin has been discontinued, these codes and features are no longer available.
