Chapter 21: A really kewl part.
So then, when Numbuhs 1 and 2 got back inside, all the KND and DNK operatives combined into a super ginormously huge robot known as...
Computer voice lady: Kids Next Door A.R.M.U.H. awesome robot meets unreachable heroics.
... and started fighting all the adults.
First it grabbed Chad, Cree, and former Numbuh 12 and tied them together in the shape of a ball. Next, it pulled out a huge energy bat and bashed the 3 of them into the next millenium. After that, it grabbed Father and hit him with the energy bat which sent him hurtling into the Sun. But, since Father has flame powers, he was able to survive on the sun. Then, the Toiletnater came running up as fast as he could and started hitting the a.r.m.u.h. as hard as he could (which wasn't really all that hard). So then, the KND a.r.m.u.h. pulled out a giant fire hose from nowhere in particular and blasted the toiletnater all the way to the sun where he was justly roasted to a crispy golden brown, then Father came over to him and turned him into ashes with his flame powers.
But then, back at the Moonbase, all the remaining villains stacked up into a giant super robot samari just like the KND's giant sooper robot samari and started kicking butt and destroying the Moonbase. But, luckily, since the KND had 'homeowner's insurance" they didn't really take a huge financial blow.
