This collectible should appear for every member, and is unlocked by playing any of the following six games.
Of these I would suggest Sifu, as it recently received added an arena mode. This is a free update available to all players, so even if you beat the game there is still something to do.
Yoshida also tweeted about the collectible; doubling down on their suggestions.
The collectible will be available for the next 78 days, so make sure to play one of these games before then.
