Kirby is hanging out on the Goodbye! BoxBoy! website

If you check out the official Japanese site for Goodbye! BoxBoy!, you might notice that Kirby stops by in Qbby form. He appears out of the 'Shop' door, which might mean that you can purchase a Kirby costume in Goodbye! BoxBoy!. For those that don't know, the BOXBOY! series lets you purchase multiple costumes for Qbby with in-game money. A Kirby costume would hardly be a stretch, considering how both franchises are developed by HAL!
