Video Game: Tamagotchi

A poster for the current Tamagotchi anime series; several of the current Tamagotchi characters are present
Tamagotchi is a series of handheld virtual pets by Bandai.

The first toys were sold in Japan on November 23, 1996. The company didn't expect much, and produced them in small number. But the toys became a big fad overnight. By the time they were producing enough to meet demand, the popularity had died down and Bandai ended up suffering financially. In 2004, they relaunched the toys with new infrared technology, allowing two Tamagotchi toys to communicate, letting them play games, exchange gifts, and even marry and produce children.

The relaunch has proven to be successful, spawning countless other Tamagotchi-related material. Two anime movies (one got dubbed), two anime series (a series of shorts, and a half-hour anime series, which is currently running; both have been dubbed at one point), music, a line of Nintendo DS games, and even two department stores in Japan. In its home country, Tamagotchi enjoys success to this day. In other parts of the world, however, the franchise has lost its popularity, slinking back down to post-1998 levels. Bandai attempted to revive the franchise worldwide by releasing it free for Android and iOS devices (in the form of the app "Tamagotchi L.i.f.e.", now discontinued) before launching a new toy and anime line, Tamagotchi Friends.

Now has a character page.

The Digimon franchise was Bandai's effort to create a Spear Counterpart to Tamagotchi, in order to tap into the male market. It... succeeded, shall we say.


Tropes from the toys and anime series:

     Toys and Franchise 
  • Aborted Arc: The US release of Tamagotchi Garden (a vintage Tamagotchi product) was cancelled after the fad ended.
    • A successor to the Music Star, called the Music Star: World Tour Edition, was meant to feature raising a Tamagotchi, forming a band, and then travelling around the world to become internationally famous. It was planned for a fall 2009 release, but never materialized.
  • The Alcoholic: Oyajitchi is obsessed with sake.
  • Alien Animals: Many Tamagotchi characters that resemble Earth species (such as Pochitchi, who resembles a dog) can be mistaken for their Earth counterparts.
  • Allegedly Free Game: Tamagotchi L.i.f.e. Tap and Hatch was a free puzzle game that offered in-app purchases. Some of the levels were nearly (if not outright) impossible without buying extra moves and power-ups, the worst offender being Level 59.
  • Animate Inanimate Object: All of the buildings, trees, and most objects on the Tamagotchi Planet are alive, or have a face at the very least.
  • Anthropomorphic Food: Several Tamagotchi characters resemble Earth food, including mochi, hamburgers, acorns, and more.
  • Anyone Can Die: It's grim, but a Tamagotchi can die as a teen, child, or even as a baby should the user neglect it enough.
  • Asexuality: The Osutchi and Mesutchi gives us Sutebotchi and Tsuketchi. They refuse to marry any Tamagotchi, no matter how old they get.
  • Back from the Dead: On the Keitai and Akai toys, the user can summon the soul of a previously deceased Tamagotchi (if one had died before) to save their current Tamagotchi from death.
  • Benevolent Alien Invasion: The Tamagotchis invaded Earth by accident (fleeing their drunk planet), but both humans and Tamagotchis ended up benefiting from the incident. The Tamagotchis deliberately returning to Earth later on is a more straight example of this.
  • Big Eater: Kuchipatchi is characterized as this.
  • Bindle Stick: Nazotchi is always seen carrying one.
  • Bizarre Alien Biology: Tamagotchis come in all weird shapes and forms, from round balls, to being a talking wine glass, to being a washiki toilet with a giant poo. However, they all eat, communicate, marry and produce offspring with no trouble at all.
  • Break the Cutie: When you don't take care of your Tamagotchi (giving it medicine when sick, feeding it, making it happy, cleaning up the poop), and if you don't do something about it quick, it might die.
  • Bribing Your Way to Victory: Later toys included items that allow the Tamagotchi to lose weight rapidly, stay happy for longer periods of time, prevent illnesses, and even live longer. Subverted, however, as these items are expensive; it would take a long time to earn enough money for them, and the only way to get so much money is to raise a healthy Tamagotchi in the first place.
    • Played straight with the new defunct Tamagotchi L.i.f.e. Tap and Hatch app; incredibly difficult levels could be beaten in seconds with the in-game purchases.
  • Brother-Sister Incest: The Mesutchi and Osutchi had no restrictions on who they're allowed to marry, so the user could potentially marry the same two units over many generations with no consequence. Doubles as Twincest, as the two babies are identical and born at the same time.
  • The Cameo: Sonic the Hedgehog shows up as an obtainable Tamagotchi on the Japan-only Sega Saturn version of the game.
  • Can't Hold His Liquor: The Tamagotchi Planet, which itself is a living Tamagotchi. It's roughly the same size as Earth, but one sip of sake is enough to get it drunk.
    • On the Keitai and Akai toys in Japan, the player can give sake to teenage characters. One sip makes them immediately get dizzy and throw up.
  • Cap: The Keitai and Version 2 toys, which introduced money to the toys, capped the money at 9999. The cap got higher for each succeeding version, with the Music Star's cap at 9~ billion. Generations and age numbers, meanwhile, always cap at 99.
  • Cast Herd: Tamagotchis are broken up into several subspecies: angels, devils, bugs (Mushitchi), fish (Sakanatchi), Ura Tamagotchi, Tama Pets, and living entities (Gaiatchi).
  • Childhood Friend Romance: Two Tamagotchis who have known each other since they were babies, and then later get married and have kids when they're adults.
  • Chocolate of Romance: On the Entama and Uratama toys, a chocolate heart can be purchased in February. Consuming it temporarily greatly accelerates the rate at which the Tamagotchi builds a relationship with another Tamagotchi.
  • Controllable Helplessness: On the earlier 2000-era Japanese toys, if the Death Spirit appears and you're not prepared with the right item to send it away, you'll be stuck sitting and waiting for your Tamagotchi to die.
  • The Corruption: Severely neglecting an Angel can result in it turning it into a Deviltchi.
  • Creature Breeding Mechanic: Certain models feature infrared connection. If two adult Tamagotchis of opposite genders are connected, they can "marry" and lay eggs that will eventually replace them. This allows players to begin the Tamagotchi life cycle over again.
  • Cross Over: With Aikatsu. The Tamagotchi toys get an add-on that feature Aikatsu characters, while Aikatsu's Datacardass game features a Tamagotchi stage.
  • Descriptively-Named Species: The "outsiders naming them" variety; Professor Banzo and Mikachu named each species as they discovered them, naming them after Earth culture and objects. After returning to their planet, the Tamagotchis adapted the naming conventions and language.
  • Distaff Counterpart: As of the V5, many characters have a counterpart of the opposite sex (for example, Mametchi and Chantotchi).
  • A Dog Named Dog: There's a character that looks like a Tamagotchi...and his name is Tamagotchi.
  • Do Well, but Not Perfect: Because the critter your egg grows into is based on how you care for it, getting a specific creature can be a tricky task. The second-best characters are reputedly the hardest to get.
  • Dub Name Change: Some characters' names are changed when the toys are translated. Some of them are simple translations (for example, "Futagotenshi" becomes "Twin Angels"), while others are for censorship (for example, "Bombtchi" became "Bakutchi").
    • The most bizarre change was for Flowertchi. She debuted on a Japanese toy and was recycled for the American V2, except they had already named a character on it "Flowertchi". So Flowertchi was renamed Korotchi, then Leaftchi, and finally Violetchi, which has stuck. Come the anime dub, it reverted back to Flowertchi.
  • Dummied Out: Looking into a Tamagotchi's ROM typically results in seeing characters that never made the cut to the final toy, but can still be accessed and raised if hacked.
    • An absurdly extreme case on the Tama-Go; there are nearly as much characters dummied out as there are ones the player can actually obtain.
  • Eating Contest: On the Version 1, this was one of the games played when two Tamagotchis connected.
  • Edible Collectible: From the Keitai (Japan) and Version 2 (worldwide) onward, different foods could be collected, many of which don't do anything special when consumed.
  • Expansion Pack: The Tamagotchi P's in Japan feature items called a "pierce", which downloads new characters, items, destinations and backgrounds into the toy. The Tama-Go in the US had a similar thing with the "Gotchi Figures"; when plugged in, they added new games and items.
  • The Face of the Sun: Sunnytchi is a living Tamagotchi sun with a face that floats around the planet.
  • Face Plant: On the Version 1, failing at the "Jump" game will make the Tamagotchi trip over a hurdle.
  • Famous-Named Foreigner: Bill is modeled after American foreigner stereotypes, and is named after Bill Clinton, US president at the time the Tamagotchi toys launched.
  • Fat Slob: Debutchi (on the Mesutchi and Osutchi toys) drools in its sleep.
  • Fattening The Victim: There's nothing stopping the player from overfeeding their Tamagotchi until their weight reaches 99, though some of the toys have consequences.
    • On the Mesutchi and Osutchi, doing this will turn the Tamagotchi into Debutchi, and if the weight's not shed off in 24 hours, it dies.
  • Follow the Leader: Their popularity in the 1990s spawned legions of virtual pets, one of the more prominent being Tiger's Giga Pets.
  • Frothy Mugs of Water: Oyajitchi's sake addiction is replaced with coffee for US toys.
  • G-Rated Sex: When two Tamagotchis are about to mate, they kiss and then the screen turns black. Fireworks will appear on the screen, and when the light comes on again, the babies appear.
  • Game Over: The death screen serves as the Tamagotchi's game over screen.
  • Genius Loci: The Tamagotchi Planet is a Tamagotchi itself.
  • The Good King: The Gotchi King.
  • The Grim Reaper: The Death Spirit, which appears on the Japanese toys when the Tamagotchi is about to die. It looks like a small, black ghost with horns.
  • Guilt-Based Gaming: If you don't tend to your Tamagotchi, it will die. You Bastard.
  • Hot Skitty-on-Wailord Action: Tamagotchi marriage can result in this.
  • Humanoid Aliens: Initially, Tamagotchis weren't very human with minor exceptions. But more human-like Tamagotchi species have appeared since they visited Earth.
  • Improbably High IQ: Mametchi and Mimitchi are characterized as having I Qs of 250 and 200, respectively. May be justified as their IQ is measured among other Tamagotchis, not humans.
  • Innocent Aliens
  • Insectoid Aliens: The Mushitchi (a subspecies of bug Tamagotchi) resemble many conventional Earth bugs.
  • Kill the Cutie: When you don't take care of your Tamagotchi.
  • Killed Off for Real: Your Tamagotchi when it dies.
  • Kissing Cousins: Could happen if you're attentive enough. It requires a long explanation, but try to keep up. If you have two tamagotchis mate with each other, the mother will give birth to two babies, one of which goes to live with the father. Both will always be of the same sex (probably to avoid any squicky possibilities). Later, you will raise the babies and eventually they will grow up and have their own kids. If their babies are a boy and a girl, respectively, they can mate.
  • Little Green Man in a Can: They live inside their plastic digital egg, as they can't survive Earth's atmosphere.
  • Loads and Loads of Characters: Each new toy introduces a number of new characters. According to the Wiki, there are over 730 different documented Tamagotchi characters.
  • Lost Forever: Many of the modern toys involve connecting with an online website or, in some Japanese cases, an arcade machine or cell phone game in order to obtain certain items. Without them, the unlocks on the toy are no longer available.
    • The most jarring example is the Music Star toy. In order to earn the special items to get the toy's secret characters, the player needs to visit the Tamatown website, earn points, buy the items, and transfer it to their toy. The website was taken down in February 2013, making them impossible to get.
    • Thankfully averted with the Japanese Entama and Uratama toys. While they did have the online website, logging in and out of it required a 14-digit number to be entered, generated by the toy. The patterns used to generate the login and logout codes was cracked, and now a freeware program known as Enwarehouse is readily available online.
    • Averted again with the Family line of pets (Version 5, V5 Celebrity). While it does have web connectivity, each item has its own unique item number, and a list of the codes has been made available online.
  • Luck-Based Mission: Obtaining Lucky Unchi-Kun on the Tamagotchi Angel is pure luck.
  • Mating Dance: The Mesutchi and Osutchi dance around when they connect to marry and reproduce.
  • Mission Pack Sequel: Many releases are basically additions to the previous version's base.
  • Must Have Caffeine: Oyajitchi (in the US).
  • Never Say "Die": In all English toys, the Tamagotchi is referred to either as "returning to its home planet" or "running away", and the gravestone and ghost from the Japanese version is replaced with a UFO and stars (or a letter reading "Goodbye"). The sequence, however, was left completely unchanged, making it clear that the pet was dying.
  • Ninja: Gozarutchi.
  • No Smoking: Several characters have been seen smoking, which have been censored later on. Helmetchi (Morino Tamagotchi) is missing his cigarette in Tap & Hatch. Memetchi's father, Memepapatchi, had his cigar replaced with a cup of coffee.
  • No Such Thing as Alien Pop Culture: Initially played straight, as Tamagotchi life was initially much simpler. Completely averted after visiting Earth, as much of the planet changed to resemble Earth, including a massive influx of pop culture.
  • Nobody Poops: Averted; your Tamagotchi leaves messes for you to clean up. Not cleaning them up will make it sick, and could kill them.
  • Office Romance: On the Music Star, the Tamagotchi may fall in love with and marry one of their bandmates.
  • One-Hour Work Week: The Entama/Uratama and V4/V4.5 all have the Tamagotchi growing up and getting a job, but the Tamagotchi can only go when you tell them to. Furthermore, they'll only be there a few minutes, and on the English toys, the job is a minigame.
  • Paparazzi: Paparatchi and Scooptchi.
  • Parental Abandonment: For each new generation, the parent from the previous one simply leaves, with no explanation. Averted for the Version 5 series, where the parents do stick around.
  • Pink Girl, Blue Boy: The Mesutchi (girl) and Osutchi (boy) toys initially came in pink and blue, respectively.
  • Plant Aliens: Some Tamagotchis are based on plants, with Kusatchi (a flower Tamagotchi in a flower pot) as one of the earliest examples.
  • The Professor: Papamametchi and his colleagues. On the Earth, Professor Banzo, who developed the Tamagotchi device.
  • Raising Sim
  • Real Person Cameo: The band GLAY appears on a limited edition version of the Tamagotchi Plus, and the band Exile appears through special items on the Tamagotchi Plus Color.
  • Regional Speciality: For the Keitai and Akai toys, food from different regions of Japan could be collected.
  • Rhythm Game: The V4/V4.5 and Music Star feature these.
  • Ridiculously Cute Critter
  • The Runaway: On later English versions of the Tamagotchi, instead of dying, the Tamagotchi would get fed up with your mistreatment and run away from home. This eventually became the case for the Japanese versions as well. A fully-grown Tamagotchi would get fed up and try to run away, and catching it before it goes gives you a chance to win their love back.
  • Santa Claus: Initially, the Tamagotchi Planet didn't celebrate Christmas. But Tamagotchis returning from Earth had picked up on Earth traditions, including Christmas, and wanted to celebrate it. A mayor of a snowy northern village, realizing there was no Santa Tamagotchi, decides to take on the role and evolves into Santaclautchi permanently.
  • Series Mascot: Mametchi.
    • Mimitchi, Kuchipatchi, and Oyajitchi have also served this role.
  • Shout-Out: A Hello Kitty doll is possible to obtain on the Keitai Tamagotchi.
    • In Tamagotchi Video Adventures, Mimitchi and Pochitchi go inside a television and play the roles of Ren and Stimpy, respectively.
      Mimitchi: YOU EEDIOT!
      Cosmotchi: Fascinating! Yet disturbing, somehow.
  • Simulation Game
  • Single-Biome Planet: The levels in Tamagotchi 'Round the World are several different planets, each hosting their own unique biome.
  • Soap Opera Rapid Aging Syndrome: Chamametchi, Kikitchi, and several other teen characters were popular enough with the target demographic that Bandai bumped them up to adults, so that the kids could play with the character longer. Though now this means Chamametchi, who is a very young girl and still in diapers, can marry and have children.
  • Solid Gold Poop: The Angel Tamagotchis produce this. Lucky Unchi-kun and Super Unchi-kun are living variations.
  • Sugar Bowl: The Tamagotchi Planet.
  • Talking Poo: Lucky Unchi-kun and Super Unchi-kun.
  • Take Me to Your Leader: Zuccitchi says this as a joke in the intro to the CD-ROM adaption. He never gets to say it to a human though.
  • The Tetris Effect: Tamagotchi effect.
  • Ultimate Job Security: On the Entama, Uratama, and the Music Star, the Tamagotchi can never lose their career once they obtain it. Subverted on the V4 and V4.5, when the Tamagotchi automatically loses their job and retires if they reach the senior stage.
  • Undying Loyalty: In the earlier versions, the Tamagotchi would stay with you, no matter how badly you treat it, until it dies. In the later versions (Music Star, Tama-Go, Tamagotchi Friends), the Tamagotchi will get fed up with you and run away.
  • Video Game Caring Potential: This is one of the game's main selling points.
  • Video Game Cruelty Potential: Of course you can go the other direction and do horrible things.
  • Year Inside, Hour Outside: Each day that passes is one year on the Tamagotchi.
    • Averted with the Santaclautchi, which measures the days, and is the only Tamagotchi to do so.

     Anime and Movies 
  • Adult Fear: Everywhere in The Movie for Mametchi's parents, ranging from Chamametchi's egg rolling away to Mametchi getting sucked inside a black hole.
  • Adults Are Useless: Played with. The parents and teachers are a big influence in the main cast's lives, offering effective comfort and guidance. Other adults, however, are more comical and unhelpful.
  • Aliens Speaking English: Justified, as they learned the language from Earth and adapted it. Initially, the Tamagotchis had a radically different language that sounded like squeaks and beeping.
  • Amazing Technicolor World: Of course.
  • April Fools' Plot: One episode had Memetchi fooling the others into thinking she was moving away.
  • Astral Finale: The series finale takes place in outer space, with Mametchi and his friends trying to cheer up the Tamagotchi Planet, to allow Tamagottsun to end.
  • Attack of the 50-Foot Whatever: Chamametchi has a dream about a giant bear attacking Mame City.
  • Awesome but Impractical: Paparighttchi, while a skilled inventor, has built a bunch of machines that fall into this category.

    • Tamagotchi! Yume Kira Dream' episode 25 for Cafe Mama.

    • Creepy Crossdresser: Himespetchi's crush on Mametchi reaches the point where she crossdresses as him. While it's unsettling to everyone else, she's not being outright malicious.
    • Wholesome Crossdresser: Melodytchi crossdresses as Oyajitchi during a summer festival.
  • Dark Is Not Evil: Kuromametchi, despite being a dark version of Mametchi, is often portrayed just as heroic and charismatic as Mametchi. Also, Blackholetchi in the movie.
  • Demoted to Extra: As to be expected with a show featuring such a large cast, many characters within a season gradually fade into the background, with the exception of the billed main cast.
  • Disney Death: Twice in the movie. First, Mametchi and Tanpopo getting sucked into Blackholetchi. When he wakes up, he's able to pull them out just fine. Later, it seems as though a giant fireball has destroyed the ship, but it turns out to be Sunnytchi bringing it home.
  • Dreadful Musician: Mametchi's awful singing has his friends covering their ears in agony. Melodytchi, oddly enough, seems to like his singing.
  • Dub Induced Plothole: Tamagotchi Friends, the official dub of Yume Kira Dream, splits the YKD episode plotlines into two 3-minute episodes. This means lots of content from the original script is ignored or erased.
  • Easily Thwarted Alien Invasion: Whatever plan the Spacey Brothers have in mind, it almost always backfires.

  • From Nobody to Nightmare: Pipospetchi could possibly be considered this, if we knew what he was saying.
    Pipospetchi: (usual language)
    Spaceytchi: R-relax, you don't have to say that....
  • Giant Food: In the second movie, one of the storybook worlds is filled with this.
  • Gratuitous English: Melodytchi.
  • Group Picture Ending: The finale ends with Mametchi and all of his friends and classmates standing on front of Dream School, waving goodbye at the audience.
  • Haunted House: In one episode, the Spacey Brothers find an old mansion with the usual moving furniture and windows that suddenly fly open. Of course, Akaspetchi is terrified, but as it turns out, the house itself was actually mechanical, used for a set in an episode of Gotchiman.
  • Hero-Worshipper: Orenetchi, who idolizes Kuromametchi.

    • There was also Himespetchi, who ended up forgetting all about him even though they were together for a long time and fell in love with Mametchi.

  • Powerpuff Girl Hands: All Tamagotchis with limbs have this, though will spontaneously produce thumbs or stubby fingers to make gestures (thumbs up, peace, etc).
  • Rube Goldberg Device: Mametchi has one in his bedroom. It activates a platform next to the house, acting as an elevator to his bedroom from the outside.
  • Running Gag: In Miracle Friends, Enchoutchi keeps mistaking X's disguised form for an empty vase, and puts flowers in him. Becomes a major plot point in episode 19.
  • Save Both Worlds: In the second movie, Mametchi and co have to save both the Tamagotchi Planet and the magic world inside the book.
  • Sempai/Kohai: Orenetchi considers Kuromametchi his sempai.

  • Slice of Life
  • Space Friction: Subverted in the movie. The rocket Mametchi and his friends steal has to be adjusted to a certain position to shoot the Planet's medicine, but it does so using smaller rockets on the ship's arms (to rotate) and four smaller jets (to reverse and slow down) instead of just stopping.
  • Space Is Noisy: The Tamagotchi Planet and Blackholetchi are able to talk freely in space.
  • Spell My Name with an "S": Most notably Spaceytchi. His name's most commonly spelled as Spacytchi(without the e), but there are some who spell it as Spaceytchi(with the e).
  • Speaks In Binary: Pipospetchi. Though it's probably best if we don't know what he's REALLY saying...
  • Stacy's Mom: In episode 25 of Tamagotchi! Yume Kira Dream, Patitchi suspects Mametchi has fallen in love with Cafe Mama, though these suspicions are dismissed later on.
  • Stalker with a Crush: Himespetchi toward Mametchi.

  • Trapped in Another World: The plot of the second movie.
  • Underdogs Never Lose: In episode 34 of GO-GO Tamagotchi!, Team Mamemepatchi (Mametchi, Memetchi, Kuchipatchi) arrive to the race later than the other competitors, suffer a bad start, spend almost all of the race trailing the other racers, but they end up being the only ones to finish the race..
    • In episode 19 of Yume Kira Dream, Mametchi is the underdog in the tea robot competition. He makes it through to the finals, but loses to Righttchi.
  • Unnecessarily Creepy Robot: The robot duplicate of Papapianitchi that Mametchi tries to make for Cafe Mama. It targets nearby girls and thrusts flowers in their faces while frantically proclaiming its love for them.
  • Unrealistic Black Hole: In the first movie, Mametchi and his friends encounter the space-vacuum-cleaners variety not far from the Planet. Justified as it's not a real black hole, but rather a living black hole called Blackholetchi.
