The Arkadians have rounded bottoms instead of legs. But how exactly are they supposed to be moving about? Their arms aren't long enough to reach the floor to propel them like a bile demon from Dungeon Keeper. Nor do they rock back and forth like Mr. Wobblyman from Noddy In Toyland or the animated Weebles. They just seem to glide forward. I've only seen the first episode, but somehow I'm not understanding how this is supposed to work.
