It's a LEGO Friends cat necklace that neither of us knew about, so it made me very curious. I started to look for some information on this item, which turned out to be not so easy when you don't speak Hungarian! But after figuring out "nyaklánc" means "necklace", I found a few other Hungarian online stores that offer this promo item: when you buy 2000 Hungarian Forint worth of LEGO Friends products, you'll get this necklace for free! According to one of the ads I found (http://www.edigital.hu/friends), the promotion started on August 12th and is ending today.
I hope some of you in Hungary have had a chance to get one! Let's hope this cute necklace will also be available in other countries soon.
