It's Aang the avatar and Momo the flying lemur! They came all the way from the US - and they brought a ship and a temple with them...
Lego had a licence for Nickelodeon's Avatar cartoons but they only ever released two sets - and for some reason they only were available in the US and disappeared from the shelves very quickly.
So I had to order them second hand, from the US... I want to build the two sets and then I will certainly use the minifigs for Avatar based MOCs.
