I
really want there to be a Wubwub grunt. I got excited and even wrote a few lines for him ("Hello blue friend.") buuuuut ... it's too much of an in-joke. Most people wouldn't get it. (Plus, it didn't sit right for him to be the only one with an "accent" / broken English.)
There's already a Frank, so Frankie (freaky or otherwise) is out.
Bob fits the name-scheme well and would make a good grunt name, but it doesn't quite fit this guy - he's a bit younger and geekier than a Bob.
So allow me to introduce Simon:
Thanks Darkfire, and equal thanks to everybody else for the other suggestions!
