History VideoGame / Tamagotchi

** There's also the toy [[Anime/{{Doraemon}} Doraemontchi]] and the functionally-equivalent Doramitchi.

* TheAlcoholic: Oyajitchi is obsessed with sake, which was replaced with coffee for international versions.

* AnimateInanimateObject: All of the buildings, trees, and most objects on the Tamagotchi Planet are ''alive'', or have a face at the very least.
** A lot of the tamagotchi characters themselves also fall under this, such as Crackertchi (a party cracker), Yakantchi (a tea kettle), Mousetchi (a computer mouse), Belltchi (a bell), and Shelltchi (a clam shell).

* CreatureBreedingMechanic: Most of the post-2004 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. The Osutchi and Mesutchi were only vintage release outside of video games that used this feature, performed with the metal prongs used on the Digimon virtual pets several months prior.

** A similar Japanese game, ''Discovered on LINE! Tamagotchi'' also uses this feature, with your Tamagotchi sending you a message via line that it has to go to the bathroom with a unique phrase, ranging from phrases shared among characters like "I'm gonna have an accident!" (which just so happens to be the most common one) and "I want to use the bathroom now" to character-specific ones like Violetchi's "It's not gonna smell like flowers soon...".

** Before the introduction of the more popular Kuromametchi in 2006, there was actually another Kuromametchi who appeared in the 1998 LicensedGame ''Hoshi de Hakken! Tamagotchi''. The ''Hoshi de Hakken! Tamagotchi'' looks a bit like WesternAnimation/MickeyMouse due to his black suit with mouse-like ears.

** 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''.

* ExposedExtraterrestrials: Zig-zagged. There are plenty of Tamagotchis that don't wears any clothing at all, but also plenty that do wear clothes (the latter type is more common in the modern releases). One of the series mascots, Mametchi, wears a black cap but no shirt or pants, while his friends Memetchi and Kuchipatchi completely lack clothing; Lovelitchi, on the other hand, does wear a shirt.

* FunnelMouthedCephalopod: The predator octopus on the Tamagotchi ocean has a funnel-shaped mouth.

* PottyEmergency: On ''My Tamagotchi Forever'', your Tamagotchi will send you a warning saying "I have to go to the toilet. Quick!" when its toilet meter is low. If you ignore this message after two hours, the Tamagotchi will poop on the floor (though sometimes the accident will occur beforehand).

* {{Paparazzi}}: Paparatchi and Scooptchi.

** Prominently with VideoGame/{{Aikatsu}} and Creator/{{Sanrio}}. The Tamagotchi P's has several add-on that feature Aikatsu and Sanrio characters, while Aikatsu's Datacardass game features a Tamagotchi stage; and there's an entire m!x version dedicated to Sanrio characters.
** The 1997 Mothra Tamagotchi, released as a tie-in to ''Film/RebirthOfMothra2'', allows the player to raise various {{kaiju}} such as Mothra and Godzilla.

** The Tamagotchi Nano model, introduced in 2010, has been reused for numerous crossovers since. These include [[Ride/DisneyThemeParks Tokyo Disney]] Easter mascots Usatama and Usapiyo, [[Creator/{{Sanrio}} Gudetama]], [[Franchise/{{Pokemon}} Eevee]], VideoGame/PacMan, and Anime/NeonGenesisEvangelion.

** Averted with the Santaclautchi, which measures the days, and is the only Tamagotchi to do so.
