There is a hidden minigame in Pokemon Yellow called Pikachu's Beach
In the 90s, Pokemon swept in as the new, super popular video game. It was a phenomenon. You had to catch them all. Serious Pokemon aficionados may think they know all there is to know about the games, but they may be wrong.
It turns out there is a somewhat hidden minigame in Pokemon Yellow. It is called Pikachu's Beach and can only be played after following a series of steps. First, the player must obtain a Surfing Pikachu. Then they must bring this Pikachu to the Surfer Dude at Summer Beach House on Route 19. From there, they are able to play Pikachu's Beach. A common way of gaining a Surfing Pikachu is to transfer one from the Stadium.
