You have two options how I see it: you either take a break for a few issues to give yourself some time to think or you come up with a creative way to get into the ending before you run out of ideas and can't think of any possible way for you to get the story to a resolution.
Ok, I have to make my ENTIRE `Shroom section tomorrow, which shouldn't be to hard, mainly due to the game I'm doing, but I predict the next section after that will either be in September or I'll get to making an August one but miss September, having the section after issue 173 being in October...
Close (also your skipped one seems to be a Minecraft skin or a very square NPC)! It was Goombario! Anyways, BACK TO ULTIMATE CHALLENGE!!! The picture is not at 90px blur:
The clue revealer (my wit has run out) tells you clues that point to a thing, wether it be a car or a building, or even a cat or Kirby, and the first one to guess it correctly becomes the next clue revealer and says clues that lead to something else, though we should keep it to more general...
I only can feel obliged to say you should problably publish a book one day, manly cause I wanna read World of Plight from the begining without going back to old issues of the `Shroom.
