Where do you get the Blonde Side Tide on Club Penguin?

You have to wait for it to come back into the catalog, or get a code and get it for free. Codes are found at the store. I have the blonde pigtailed hair, and it took a year and a half for it to come back to the catalog for me to finally get it. I have seen it in the catalog 2 times, once as a "non"member, and once as a member. Just hope that it comes back in time so that you have enough coins and you are a member. It might not ever come back to the catalog, though. Hope this helps!
