Sweet, a tea pot droid for the very thirsty jedi.
It reminds me somehow of the tea-drinking robot I saw in the trailer of "Armed & Dangerous".
I've just discovered the item "HK-47 Hull 4" in my inventory of an old save game.
I don't know where and why I got it, though. I'm sure I've never had it in my other games. It has defense bonus, immunities and regeneration and some other things. Unfortunately, it is unequipable. Perhaps it has something to do with repairing HK and it was accidently added to my inventory instead of only changing HK?
Here is a screenshot:
