Japan-Pet is a running joke on the Nations Official Forums . It was originally drawn and published by Freezepond via a thread by Prussia titled "Community Memes [Idea] " in a one-panel comic parodying television infomercials. Hirohito later "endorsed" the Japan-Pet and has since been mentioned in several other posts.
Japan-Pet is a special television offer toy that features 100+ catchphrases, 8+ inches diameter, and expression changing eyes that can glow red by burning a combination of magnesium and mercury, that is known to cause blindness. Other accessories are sold separately. Calling in during the commercial will double the offer, giving two Japan-Pets for the price of $19.99, plus shipping and handling.
