[[caption-width-right:350:Where are we off to today, Pikachu?]]

''Hey You, Pikachu!'' is a virtual pet ''Franchise/{{Pokemon}}'' game developed by Creator/{{Ambrella}} (their debut title) for the Platform/Nintendo64. It was released in December 1998 in Japan and October 2000 in North America.

One day, Professor Oak asks you to help him test the PokéHelper, a device that translates human speech into a form that Pokémon can directly understand. After using this on a wild Pikachu near Viridian Forest, [[PetBabyWildAnimal it follows you home and wants to befriend you]]. Thus start your adventures, where you use your voice to guide Pikachu as he wanders around and plays with his Pokémon friends.

The game makes use of the Voice Recognition Unit or VRU, a peripheral that picks up your voice and translates it into commands for Pikachu to follow. Most of the gameplay requires the VRU in some way, as you're mostly an observer to Pikachu's antics and have very little direct control over it.

While no direct sequels were made with the microphone mechanic, the game was succeeded by the similar ''VideoGame/PokemonChannel'' and ''VideoGame/PokeParkWii'' simulation games.

!!''Hey You, Pikachu!'' contains examples of:
* AnimalTalk: You need the Poké Helper (or the megaphone) to communicate with Pikachu, though he can talk to other Pokémon regardless of species.
* BananaPeel: Pikachu can slip on these in Piñata Party, or anytime he's careless after eating a banana.
* BerserkButton: Pikachu hates being called a rat.
* ABoyAndHisX: The core of the game is the player learning about the bonds between people and Pokemon, exemplified by their relationship with Pikachu. [[spoiler:When it's finally time to let Pikachu go, it refuses to leave and stays with the player.]]
* ConsoleCameo:
** A Nintendo 64 can be found in the bedroom.
** In the Japanese version, it seems to be able to use [[Platform/SuperNintendoEntertainmentSystem Super Famicom]] cartridges.
* CulturalTranslation:
** The cupcake that Pikachu steals from you was originally an onigiri.
** Piñata Party was originally a watermelon-splitting game with similar rules called [[http://en.wikipedia.org/wiki/Suikawari suikawari]].
* DefeatMeansFriendship: Averted. You befriend Pikachu without battles or Poké Balls.
* ExtremeOmnivore: Pikachu again. Especially annoying when he grabs the megaphone out of your hands and eats it only to wince with a disgusted "Pii-yuck!". He has so little knowledge of what's edible that [[TooDumbToLive it's amazing he can survive in the wild.]]
* FakeDifficulty: It can be an ordeal to complete basic tasks in the game because the voice recognition just won't understand you or because Pikachu just does whatever. One of the most frustrating examples is trying to buy something from Abra's shop, where often times Pikachu will just pick something else out regardless of what you try telling him to get, and then you can only visit Abra's shop once in a day, so if Pikachu buys the wrong item, you'll need to wait until the next day before you can get another chance at buying that Lucky Hook.
* FishingMinigame: And you can win posters to hang on your wall if you do well enough!
* GuideDangIt: Some of Bulbasaur's cooking ingredients. To be specific, the game told you three ingredients necessary for the recipe. The GuideDangIt? ''There were always FOUR ingredients, but the game would never tell you that.'' On the plus side, the fourth can be anything edible, but some go better in some recipes than others, making for another GuideDangIt.
** Another moment of this is unlocking Cobalt Island for the treasure hunting activity. The game never tells you that, in order to unlock Cobalt Island, you (or rather Pikachu) have to break open the piñata ''three times''! If Pikachu fails to break it open even once, you have to start all over (since the game only allows you three chances per visit). The piñata mission is already regarded to be the most [[ScrappyMechanic annoying mechanic]] to complete due to the awkward hitbox of the piñata itself. Because of this, there are those that mentioned that they didn't even know Cobalt Island existed to play on.
* HammerSpace: Where Pikachu gets his pad of paper and drawing utensils.
* HarmlessElectrocution: Hitting you with a thunderbolt is Pikachu's way of playing tag.
* {{Hypocrite}}: Professor Oak's order [[spoiler: to release Pikachu]] in the end seems odd considering his goals involve people building friendships with Pokémon.
* ImprobableAccessoryEffect: Some of the uses for the megaphone make perfect sense. You can use it to call Pikachu when he steals the Poké Helper, call lost Poliwag over to you, or scare away the Haunter. On the other hand, you can also use its speech bubbles to... knock fruit out of trees?[[note]]You ''are'' supposed to have Pikachu use Thunderbolt or Thunder, but, GoodBadBugs strike again[[/note]].
* AnInteriorDesignerIsYou: Stuff you collect in the levels can be brought back home into the room and back garden. The player doesn't really decide what goes where, but you can play with Pikachu using them.
* LightningCanDoAnything: Including turning corn on the cob into popcorn -- complete with a bag.

* MarketBasedTitle: The Japanese version of the game is called "Pikachu genkidechū", literally meaning "Pikachu Is [[PunBasedTitle Fine-achu]]".
* MythologyGag:
** Ash's outfit from the anime can be found hanging on a coat rack in the bedroom. Pikachu uses the hat to cover his eyes in Piñata Party.
** The player's mother looks just like Ash's mom, Delia.
** Who's That Pokémon is a MiniGame that can be played in the bedroom. And one particularly ambiguous silhouette may turn out to be [[spoiler:[[Recap/PokemonS1E56TheUltimateTest Jigglypuff seen from above.]]]]
** [[spoiler:The ending appears to be a {{homage}} to the anime episode "[[Recap/PokemonS1E39PikachusGoodbye Pikachu's Goodbye]]"]]
* NintendoHard: The piñata game is ''extremely'' hard to win, especially the variation that has multiple rounds.
* NoNameGiven:
** The user is only ever spoken to in second person.
** You can't name the Pikachu, so you have to refer to him by his species.
* OddlyNamedSequel2ElectricBoogaloo: The game's title; it was the only game in the franchise without the prefix "Poké" in its name until ''VideoGame/PokkenTournament''[[note]]technically cheating there because all it does is add another k[[/note]] and ''VideoGame/DetectivePikachu''.
* PatternCodedEggs: A Togepi egg, white with red and blue triangles, can be found and hatched while completing the Pokémon Picnic missions.
* PunBasedTitle: The game's Japanese title translates to literally "Pikachu Is Fine-achu".
* RainbowSpeak: Words Pikachu understands are in red. The word "Pikachu" itself is yellow.
* ReadTheFreakingManual: What most players don't realize is that Pikachu will ''only'' react to words that are marked in red. It doesn't necessarily make the game easier, but it helps streamline the experience tremendously.
* RegionalBonus: Popcorn is only obtainable in the U.S. version. This is because the Japanese version has eggplants instead of corn.
* RidiculouslyCuteCritter: Pikachu -- and if you tell him so, he blushes, making himself even ''more'' adorable.
* ShakingTheRump: Pikachu sometimes does this to the Caterpie he's babysitting for no real reason, presumably to amuse them.
* ShoutOut: The final mission has the player [[VideoGame/MetalGear following Pikachu inside a cardboard box]].
* SugarBowl: The game takes place in an idyllic forest full of cheerful, frolicking Pokémon.
* UniversalTranslator: The Poké Helper seems to be one, at least in terms of human to Pikachu.
* VideoGameCaringPotential: Giving Pikachu compliments, getting Bulbasaur's picnic ingredients right, buying fun stuff at the shop...
* VideoGameCrueltyPotential:
** You can bully the poor little guy by encouraging him to eat garbage, yelling in his ears with a megaphone, and calling him "electric rat".
** There's a graphics glitch where you can make it look like a sword is going through Pikachu.
** During the mission where you babysit for Butterfree, you can wait for the Caterpie to get hungry and just let them suffer.
** You can yell extremely vulgar things at Pikachu... through a megaphone.
