A new type of nugget is coming to McDonald's Japan, but it's not on the menu.
Starting this summer, the company is launching a contest in which customers can win a $2,000 gold nugget.
The nugget is part of McDonald's Japan's campaign to launch a new character: Kaito Nuggets, which translates to Phantom Thief Nuggets, The Huffington Post reports.
The new character -- somewhat reminiscent of the classic McDonald's character the Hamburglar, wears a black mask, top hat and a yellow suit with a red bowtie.
To win the nugget, The Huffington Post reported participants have to help find out who is behind Kaito Nuggets' mask and post where he's found with a hashtag that translates to "Kaito Nuggets," according to an emailed release.
USA Today reported that "Kaito Nuggets appears in some McDonald's restaurants throughout Japan to hunt the ... great-tasting sauces … or he will throw out a ceremonial first pitch in a professional baseball game," according to McDonald's Japan's statement. "He will appear every here and there."
Those "great-tasting sauces," which the contest also promotes, are a Creamy Cheddar Cheese Sauce and Fruits Curry Sauce.
Only one person will win the golden nugget, but 21 people will win a coupon for free five-piece nuggets.
