What is the code to unlock the black puffle in club penguin?

You really do want a Club Penguin puffle right? So do the ones who actually buy the puffle codes. I am pretty sure they like puffles for themselves and will want to use the code themselves. So its useless to ask if somebody can give you a puffle code as no one will do so. All the codes they will give out will either be used or fake. Its true, would YOU want to give it out to anybody else if you got such a code?
