The PCs managed to take Thweek's ship at the end of "Long Arm of the Hutt," and wants to learn more about them, however, the only in-game resource we can find on them IS the writeup for Thweek's. Are stats for a stock Dunelizard anywhere?

The book “Lords of Nal Hutta” has the Mandalmotors M3-A Scyk (see http://swrpg.viluppo.net/transportation/starships/1823/ ), and according to what Wookieepedia says about it (see http://starwars.wikia.com/wiki/G1-M4-C_Dunelizard_fighter ), the Dunelizard was an improved version of the M3-A, with heavier payload and shields.

So, if nothing else, it shouldn’t be too hard to create your own stat block for the Dunelizard.
