It seems the fellers tried blasting off for Mars any number of times over their years with Kelly. Because that's the gimmick of this whole Pandemonia thing, here are some pages from the fifties that saw print in a Dutch fan publication, StripSchrift. Great thanks to Norman Boyd for sending over this Dutch treat.
You don't need to know Dutch very well to be able to follow along, in fact 'Gobby Wombies' translates pretty well.
