Agatha first tasks the little guy with seeing what it can do with a declanked Fun-Sized Mobile Agony and Death Dispenser. as it turns out. Deuce also doubles as a compact when Agatha wants to check her appearance.
"Deuce Dingbot" is the 2nd model of prime Dingbot clank created by Agatha. Based on her favorite design, it is hard to distinguish in appearance from her other prime clanks. At least some of the prime Dingbots seem to differ in their limbs, especially in the number and size of the arm's hinges.  We would have thought it to be Dingbot Prime except we know that one is.
The Castle is nervous about Deuce, but, as Agatha , "It's just one little clank!" What could possibly go wrong?
