Nintendo Labo may have taken the gaming world by complete surprise, but one Japanese player was exploring the joys of cardboard construction as early as October last year.

Twitter user masaki_samurai posted the following video of his child playing with a specially-constructed gun in Splatoon 2. OK, so it's not quite the same deal as Labo, but the way in which the Joy-Con slot into the gun itself is quite similar, and it hints at potential applications of Labo kits in the future.

For example, what is stopping Nintendo from producing a special Labo kit for Splatoon 2 which does the same thing, or creating accessory kits which augment other, non-Labo titles?

Even if Nintendo doesn't take this route, it's a very interesting case which just goes to show how versatile the Joy-Con controllers are.
