Pretty sure the R5 series - of which R5-D4, the red astromech with a bad motivator from the original movie, was the first we see - doesn't have arms coming out of the head. Looking at Chopper alongside Artoo in that one episode in season 1, the two chassis (not sure of the plural) are different, whereas R2-D2 and R5-D4 had near-identical chassis except for the head.

But that reminds me of one line from a SWSE game....

(all OOC)
Me (playing a techie): Okay, I'll need a mouse droid chassis and five kilos of detonite.
GM: Five kilos? Isn't that a bit excessive?
Mando Player: There's no problem that can't be solved with too much detonite.
Me: Unless you want me to roll to make a baradium warhead, instead."
Mando: Baradium's underrated. And illegal, even in Hutt space.
Me: So is this kamikaze mouse droid. :)
