The Rancor is not official, it's the monster from the Rock Raiders line, and the Wampa is from an Orient Expedition set, but you added horns. Still nice, I wish I had them (but I have that monster, LOL..)
Nice, but the 'wampa' is an ice monster from a jonny thunder set and I don't know about the 3rd one but I don't think it is official lego star wars. I still like them though. I really want that Dewback!
