Alliteration is in the name of the game.
Following its release in Japan earlier this year, the West will soon have its opportunity to say farewell to BoxBoy.
Nintendo's UK news page lists "Bye-Bye BoxBoy!" as releasing on 23 March for 3DS. The entry currently goes to a 404 (file not found) page when clicked.
As of yet, no details have been announced for North American release, nor the status of the retail collection of the three eShop titles and a BoxBoy Amiibo.
Thanks to @Wario64 for finding this.
