Nothin' Doin'

Another action packed summer day. I spent most of it playing KOTOR, but I kept getting killed by this dumb Rancor. Somehow I have to feed him something that will kill it, but I can't figure out how to make it eat things. This whole thing would be a lot easier if I just looked at the online walkthroughs, but I refuse to use them out of principle. I mean, otherwise, what's the point?
