They are called "head tails."
Q. What do you call the disgusting pig creature's that Luke chokes in RoTJ? (Motti-sol, don't answer since you've played KOTOR)
How I hate the Pig Creatures!
And BTW, there is no "nuetral" ending. Even if you kill Bastila she is there in the ending sequence.
Now. I order you to go out and buy KOTOR and an XBOX if you don't have one.
