Ever since my son started to play the Lego Star Wars video game on the Nintendo DS, he's been a fan of Garindan (Long Snoot). I remember that even I as a kid I liked that character even though we only see him for a few seconds in the original 1977 film.
Garindan works for the highest bidders. It can be the Empire or even Jabba the Hutt but he does get the job done. Actually he is the one who informs the Stormtroopers where Luke and Ben are meeting Han & Chewie in the Falcon. Hasbro released the figure in 1997 and needless to say it as become one of my son's favorite.
