Pokka Mario Bros.

Pokka Mario Bros. is an extremely rare Game & Watch video game that was used in promotions for the Pokka food company. Only 500 units were created, and it's unknown if every single one was given away. The only way to get one way back when was to come in possession of a certain amount of food coupons and then bring them to a certain retailer, where they would then give you the unit. Of all the Game & Watch games, Pokka Mario Bros. is one of the rarest. The game was part of the "multi-screen" series.
