The giveaway this time around will be a loose (as in just the cart--no box, case or manual) copy of Pony Canyon's GameBoy port of Sega's Doki Doki Penguin Land, which drops the Doki Doki in favor of simply being known as Penguin Land.
I've written about this game a few times before now, by the way. I first mentioned--and showcased a video of--it in this post, and then I spent some time chatting about its packaging in this post and its instruction manual in this post.
So, you may want to check out one or all of those previously published posts before you decide whether or not you want this cart.
Should you decide that you do want it, just leave some sort of a comment below between today and the morning of Monday, June 23. Even a simple "yo!" is OK if your username is unique enough that I should be able to tell you apart from all of the other people clamoring for their very own copy of Penguin Land.
