Hey You, Pikachu!^[a] is a virtual pet Pokémon spin-off video game for the Nintendo 64 developed by Ambrella and published by Nintendo. It was released in Japan on December 12, 1998, and in North America on October 30, 2000. The player is asked to help Professor Oak test the PokéHelper, a device that lets humans communicate with Pokémon. The game is set in the Kanto region between Pewter City and Viridian City, where the player is introduced to a wild Pikachu. The player is able to communicate with a 256-word database through the Voice Recognition Unit (VRU), a Nintendo 64 hardware accessory that, when paired with a microphone, can comprehend and analyze human speech.^[2] Along with speaking with Pikachu, the VRU allows the player to move around and gather items.

Hey You, Pikachu! is one of only two games to utilize the VRU, with the other being Densha de Go! 64, the Japan-exclusive N64 port of Densha de Go! 2 Kōsoku-hen. The game had a mixed reception from critics. Though no direct sequels have been made, the virtual pet game Pokémon Channel, first released for the GameCube in 2003, resembles Hey You, Pikachu! and shares similar gameplay, with the exception of the microphone peripheral.

Gameplay

The main character is asked to test out the PokéHelper, a new device of Professor Oak’s that is used to talk to Pokémon. The player then meets a wild Pikachu and befriends it. Once the player earns Pikachu’s trust, it will come and live in the player’s house. There are three different activity days: Pikachu’s Daring Days, Discovery Days, and Play Days. Each day has a different objective (e.g. collecting food, going fishing) and the player can earn Pika Points, the currency used at Abra‘s Shop to unlock new items.

After 365 gameplay days, Professor Oak notifies the player that Pikachu, still a wild Pokémon, must be released. The player ventures to the woods to find Pikachu and repeatedly says “goodbye”, upon which Pikachu realizes it must return to the wild. After the credits, while the player looks around the front yard and reminisces, Pikachu returns, and the game continues as if Pikachu was never released.
