My favorite level is (by far) the one where you go after Borvo the Hutt.
When the level is finished, though, I notice that there is a bonus required for a gold medal! I've kept my eyes open, but still haven't seen anything that looks like a bonus...the only part of the mission where there would be enough time would be the middle, while you're looking for Borvo with Kolkassa's (sp?) help.
Where is that bad boy, anyway?
