A promotional cookie was included in press kits for Metroid Prime 2: Echoes in 2004. It was a white, round cookie with the game's logo printed in the middle and covered with small black rocks, which are possibly crystallized sugar or another candy. Its flavor is unknown, as is who baked them. One of these cookies, still in its wrapper, was placed up for auction on eBay for $129.99 USD in 2011, although by that point it is reasonable to assume that this cookie was no longer edible, and no other such cookies have surfaced online.
