The first souvenier I bought was an 8" troll figurine. I bought two more during my trip. Because I already had one, I now have 4 official NyForm Trolls:

The first one I bought (the one with the droopy nose) was around 128 Kroner, which is about $18. Norwegian money is fun! Here is a 50 (femti) Kroner bill, then in order from left to right a: half krone, one (én) krone, five (fem) kroner, ten (ti) kroner, twenty (tjue) kroner.
