Waluigi Time is absolutely correct! We're working away to make sure the issue is a full-on special, with plans for some special sections, graphics, and activities to reflect the theme. We'll have a few surprises, and we'll have a few more announcements as the issue approaches, so please keep an eye out.
I admire your enthusiasm, though!
I think Waluigi Time has some great suggestions for your section for issue 171. You could also consider going through old editions of Palette Swap and making trivia questions about them.
As for a contribution to Palette Swap itself, since you're a Kirby fan, maybe you could introduce us to your favorite Kirby themes? Palette Swap is pretty light and simple - it should be about the joy of sharing creative works with others, so I suggest picking something you enjoy and that you're eager to share!
