Maybe it's a little lump. Maybe it's a sharp angle. A gangling to chain around the corner, a high, giddy laugh. The thunk tink of a booted foot and a pegleg- but they aren't stealthy. They aren't silent. Hard to be when you're half metal and mostly explosives bouncing around hallways or blinking with pretty little red lights- but they're there.

At the end of the hall riddled with beartraps, in a corridor lit up red from mountains upon mountains of bombs- or a hook slinging through the air aimed right at you-

These two are up and pumped and intent on causing all kinds chaos. Nice looking little whatsit you got there. Terrible if something happens to it- like. It blowing up. Or getting yanked away by a hook. Or blowing up!
