Well the arms are looking a lot better. Hmm... well we could try another idea. How about the arms are an attachment instead of being controlled by GUS?

So not only do the little helpers try to fix all his mistakes, but so does the poor arms attachment attached to him. It tries helplessly to fix things independant of him completely even though it's attached to him still.

Maybe he'll walk away from the table and the little arms will be struggling like a person to reach and grab for the table to stop it from falling and when it crashes to the floor, it drops the arms as if it just gave up...

You should give it little fingers too. To give it some personality as a seperate independant character from GUS.

Oh and one more thing, the outter shell on this guy is gotta have a bit of rust on it. Nothing looking like it's new. Like parts that were nice and clean, but over the years growing rust on it...
