Cave People

In Star Wars Episode 1 Racer several of the tracks take place place on Malastare, a planet mentioned twice in TPM and also where Sebulba comes from.
In the game it is portrayed as being dark and ROCKY with CAVES. This could be one of the new planets that we get to see in Episode 2.

Does it have a big population? The rumors I read made it sound like the cave people would be like the Ewoks, Sand People or Gungans in that they would be primitive.

The only two species that I know live on Malastare are Dugs (like Sebulba) and Grans (the three-eyed goat-like aliens that were at the senate).
Another thing I forgot to point out is that it has massive bright luminous lakes of green liquid on it. Not that that's important, but it may play some sort of role if Malastare actually is in Episode 2 or 3.
