This began as an alternate build of the Star Wars set "Duel on Geonosis" (75017-1), but I quickly started adding pieces from the Star Wars set "Desert Skiff" (9496-1). I also added the wheels from the Legends of Chima set "Rogon's Rock Flinger" (70131-1) for the 'Wheel of Fortune' feature. ...and then I just started grabbing random parts from the bin.
The MOC features a Temple of Fire (Dooku's lightning bolt makes a nice fire), an actually spinning Wheel of Fortune (quite fun to spin), opening Gun Pods (the mouth from the Sarlacc pit), and a cockpit large enough for Dooku to fit comfortably. Enjoy!
