If you are looking for the Space Faerie BD challenger, you need the codes redeemable at the Grundo Warehouse. These are the notebooks, sticker packs and magnet sets. I bought mine from Neopets on Ebay. They occasionally have lots of items that ALL have Reedeemable Codes. If you are interested, check out the
Stuff page and click on Plushie Sets or search for username: neopetscollectables on Ebay.
Thier packages change often. I bought one that was all stickers, notebooks, and magnet sets at a much lower price than a package that included plushies and paid about $1 a code, with the actual item as a bonus
