The Pokemon Company has launched a new recycling initiative in Japan as a special collaboration with the "Pokemon Daisuki Club," which functions as the official Japanese Pokemon Fan Club. The new initiative has been dubbed "Hungry Grimer," or "Empty Belly Grimer," and it involves a particularly hungry Grimer's pursuit of a full belly.

Fans can take a look at the official Pokemon site dedicated to the project, but unfortunately, details are only available in Japanese. The site allows viewers to read about Grimer's proposed strategy for achieving a stomach full of food ("Grimer's Satiety Strategy"),  and showcases the Hungry Grimer's design: a trashcan topped with a life-size Grimer, which will apparently respond when fed.

Grimer is a Poison-type first introduced in Generation 1 of Pokemon. As per its official description, "Hungry Grimer" is a Grimer that loves eating empty plastic bottles, glass bottles, and cans. The incredibly hungry sludge Pokemon is making appearances in numerous cities, but it's doing so "like a spirit" - nobody knows where Hungry Grimer will next wander off to. That said, the site does promise that Hungry Grimer will relocate to a new site as soon as its belly is full.

Of course, these Grimer trashcans aren't particularly enormous, so its likely Hungry Grimer will stick around a location for a while even after it's been filled once. There's also no reason to believe that multiple Hungry Grimers can't be put up at the same time, though the website's language does imply that this will be a traveling Pokemon phenomenon, rather than one that multiplies as it expands.

Hungry Grimer will allow a passerby to reach into its mouth and feed it some recyclable trash. Depending on the kind of trash fed, Hungry Grimer will reply with a unique vocal response.

Needless to say, fans are speculating that Hungry Grimer may appear as its Dark-Type Alolan variant in future cities, or may even evolve into Hungry Muk after they're fed enough trash. That said, it's still very likely that these Hungry Grimer won't make it out of Japan. Generally speaking, these elaborate real-world Pokemon events tend to take place in Nintendo's homeland.

Insofar as their responses, videos floating around Twitter seem to indicate that Hungry Grimer will make various sorts of chewing noises before ultimately trying to identify the object it was fed. The video above shows someone feeding Hungry Grimer a Real Gold energy drink can, which it proceeds to "gobble" up before finally crying, "Bin!" (Japanese for bottle). Evidently, Grimer's strengths don't include a well-defined palate, but as long as it enjoys the recyclable trash, does it really matter that it can't tell the difference between a bottle and a can?
