With Science, Lego and a hint of Magic :D Anyway the pieces are from a variety of other minifigures, the helmet's from the most recent Power Miner's sets and the torso is Space Police, just look up the rest on Bricklink and you should be good :D
Neat! I loved the Mustafarian! Hardly anyone makes Mustafarians as good as you do! Do you mind if I could use that technique of Mustafarian building in my next MOCS? I will give credit.
Anyway I liked the lava river and the little room for the seperatists! I give it a 999 out of 3 :)
