Not to be confused with Memetchi. Mametchi (まめっち Mametchi) is a male adult Tamagotchi character who debuted on the original Tamagotchi, and has appeared on many versions since, serving as the series mascot. Mametchi is in the Mame Family (まめ属 Mame Zoku) and his birthday is November 23, the same date as the release of the first Tamagotchi. On almost every Tamagotchi model, he is the healthiest adult character, obtained by perfect care.
Mame (まめ) means diligent, but is often also interpreted as soy bean (豆 mame) (for example, see his Chinese names below), which possibly is a reference to his color scheme.
Names in Other Languages
|Cantonese (Hong Kong)||豆豆|
Mametchi is light yellow and has a wide, round head with a narrow body and large, black eyes. He has two arms, two legs, and two large bumps resembling animal ears covered in black fur on top of his head. As of 2004, he has rosy pink cheeks as well as dark blue eyes and ears and in the anime he has a slightly longer body.
When Tamagotchi first launched in the US, Mametchi was classified as a female instead of a male and had a much leaner build, a smaller head and eyes, and a blue body. These changes were eventually abandoned and Mametchi's original Japanese appearance has since been maintained worldwide.
In Tamagotchi L.i.f.e., he can be yellow, pink or blue.
Mametchi is a very healthy adult Tamagotchi who is likely to have a long life. He is extremely clever with an IQ of around 250. He is a serious prodigy type, and one of the smartest Tamagotchis. His hobby is creating inventions and though sometimes they fail, he will keep making them. He's not very good when it comes to painting.
The Tamagotchi Record Book also describes Mametchi as being extremely serious, well-mannered and very clever; but adds that he is inflexible on some issues.
According to Tamagotchi Connection: Corner Shop 3, Mametchi once stole some candy when he was younger, implying that he used to have a mischievous side.

Anime TV de Hakken!! Tamagotchi
Mametchi is a recurring character in Anime TV de Hakken!! Tamagotchi. Of the 9 episodes that have sufficed on home video, Mametchi plays starring roles in 2 of them.
In the 3rd episode, Mametchi and Ginjirotchi are seen eating at a restaurant. They order 4 different meals, and while Ginjirotchi is enjoying his orders, Mametchi's orders keep getting eaten while he thanks Kuchipatchi for delivering them. The 3rd order reveals that Nyorotchi is the one eating Mametchi's food, and Mametchi tries to keep him away from his 4th order by running away from him, but Nyorotchi ends up snatching the food and ends up getting ill from eating too much. Mametchi and Ginjirotchi then contact the hospital, and after Nyorotchi gets cured by Tarakotchi and Maskutchi, everyone, including Mametchi, enjoys a meal together.
In the following episode, Mametchi takes the role of a traffic director. He tries helping Ginjirotchi back up, which leads to him bumping into Kuchipatchi, and later helps Tarakotchi and Zuccitchi go forward, causing the latter to bump into the former.

The two later settle with the flower and leave behind a golden egg, which the cat then plays with.

Tamagotchi: The Movie
In Tamagotchi: The Movie, Mametchi accidentally transports Tanpopo, a human girl, to Tamagotchi Planet after a mishap happens with his transporter machine. While Mametchi and friends show Tanpopo around Tamagotchi Town, it's revealed that Mametchi is soon going to be a big brother and that he's scared of the dark due to getting trapped in a pit when he was younger. The transporter machine was originally meant to transport Sunnytchi (the sun) to him so he wouldn't be scared in dark areas.
Later on, Tanpopo and Mametchi chase after his sibling's egg which has rolled all the way to the top of a tower. They succesfully retrieve the egg after their friends rescue them from a dangerous fall and the egg hatches into Mimifuwatchi which then evolves into Chamametchi the next day. In that time period, Mametchi creates Mamesunnytchi, a smaller version of the sun. The following day, it's revealed that Sunnytchi has disappeared, causing Tamagotchi Planet to get a cold and nighttime to stay. Sunnytchi left a letter implying that Mamesunnytchi's creation caused him to leave which upsets Mametchi and makes him run off in tears, believing he caused the situation.
Determined to make things right, Mametchi, Tanpopo, and Chamametchi (who snuck aboard) ride a rocket to space to bring back Sunnytchi. After delivering a cold-curing pill to Tamagotchi Planet on Mamemame Laboratory's request, another problem arises. The rocket is being sucked in by Blackholetchi who is asleep and doesn't realize the danger he's causing them. Mametchi and Tanpopo go outside the rocket to pry a meteor off the speaker so they can wake up Blackholetchi and they successfully do so with Mametchi getting over his fear of the dark. Unfortunately, they are sucked in before they can shout at Blackholetchi so the population of Tamagotchi Planet and the planet itself shout at them instead, waking him up. Mametchi and Tanpopo are freed and Sunnytchi appears to bring the rocket back home, explaining that they left to go on hot spring tour.
Mametchi, the other Tamagotchis, and Tanpopo enjoy themselves at Gotchi King's birthday, but Mamametchi and Papamametchi inform Tanpopo that a comet taking her back to the Earth will be arriving soon. Mametchi and the others then bid a tearful farewell to Tanpopo, and in the post-credits scene, Mametchi sends her a message on her Tamagotchi device.

Tamagotchi: Happiest Story in the Universe!
In the second movie Tamagotchi: Happiest Story in the Universe!, Mametchi and friends encounter the Magical Flying Library Ship piloted by Otogitchi and his sister which has storybooks that suck them in. They go on adventures in the stories, playing as the main character. After Memetchi and Makiko get into a fight over the prince who has been in their story, Mametchi gets inspired and tries to create a happy machine. Due to some mishaps, he ends up creating a living being called Hapihapitchi instead who has the power to make people happy. She goes around Tamagotchi Town making people happy, but Mametchi noticed that people fully depend on Hapihapitchi to solve their problems instead of working it out themselves. Thus, Mametchi asks her to not use her powers anymore until he can figure out a better solution.
The flying library comes to school again and this time, Mametchi and friends are sucked into a book titled, "The World's Happiest Story". Unlike the previous stories, they are not the main character. The main character is instead Happy, a man who is determined to become the happiest man in the world. They follow him on his journey and try to help him, but he refuses their help. They also notice that the story loops and never ends, and they're forced to leave when the school bell rings to bring them back to class.
Later on, Mametchi sees a tornado of paper engulfing Celebria on TV, caused by Kikitchi entering the previous book by himself at home. Mametchi goes to Mamemame Laboratory to figure out how to solve the problem and it's discovered that the storybook is unstable from the last page being ripped out and Kikitchi entering the story. Papamametchi then allows Mametchi and his friends to enter the story to rescue Kikitchi as Otogitchi goes to write the last page with his magic crayon. Unfortunately, the endings Otogitchi tries to write don't work and the magic crayon is lost as the world inside falls apart. Mametchi allows Hapihapitchi to use her powers on Happy and this, along with Kikitchi's help, allows him to find his true happy ending and actually become happy.
Suddenly, Hapihapitchi collapses and Mametchi realizes that she doesn't have any happiness left and would die soon. He asks everyone to be happy so she can become better, but everyone is too sad over the grim situation. Luckily, Happy gives her all his happiness and she springs back to life. Mametchi is later seen with his friends celebrating their success in Tamatown.
In the anime series Tamagotchi!, Mametchi is the main protagonist along with Memetchi, Kuchipatchi, and Lovelitchi. He often has a main or secondary role in episodes and throughout the series he makes inventions to help his friends out. In "It's a Secret! Mametchi's Birthday", Mametchi becomes upset from everyone except Lovelitchi avoiding him. Lovelitchi tries to help him out and eventually his friends explain that they were just planning his birthday party and apologize for making him upset. This causes Lovelitchi to realize that she doesn't want to keep her Lovelin persona a secret from her friends and she tells the truth at Mametchi's birthday party in "Listen! Lovelin's Confession". Mametchi and friends accept this and promise to keep the secret between everyone that was at the party.
In "Time Slip! Jungle Tamagotchi Planet" Mametchi and friends get sent to the past after the Kuchipatchi of Truth leads them to it by sending messages on Lovelitchi's phone, Telelin. The group discovers that that the Tamagotchis in the past era are suffering from plants that have taken over the land and Mametchi helps Mamemametchi create a machine to fight the overgrowth. After saving everyone, the group is sent back to their time along with Telelin who is now sentient.
In "Hello! Big Mix-up in the Profile Machine?", Mametchi creates a machine to generate profiles for Lovelitchi and Melodytchi. However, the machine malfunctions and brings a girl called Tomomi from earth instead. Mametchi works to find a way to send her back and along the way, learns about the legend of the tama hearts: magical objects that must be collected to prevent Tamagotchi Planet from falling to a dangerous curse in the future. Mametchi creates a new version of the Tama Profys for Lovelitchi and Melodytchi and the group go on adventures to recover as many hearts as possible in the Profys. A mysterious being called Kizunatchi is created from the Profys during that time. Eventually, Mametchi is able to successfully send Tomomi home with a teleporting machine.
After Tomomi leaves, a new student called Himespetchi transfers into Tamagotchi School. Upon seeing Mametchi she immediately falls in love and is obssessed with him, though Mametchi is oblivious to this. Mametchi and friends manage to eventually collect enough tama hearts as the egg curse starts to take place and transform all Tamagotchis into eggs. The group hurries to Ha Island in to place the hearts in the Heart Pillars to stop the curse before it's too late and Kizunatchi proceeds to save everyone using the power of their strong bonds with each other.
After a tearful farewell to Kizunatchi, who stayed behind on the island to protect the hearts, Miss Perfect tells Mametchi's class that since Mametchi, Memetchi and Kuchipatchi won the soccer tournament, they will be moving to Dream Town to go to a new school, much to everyone's astonishment and Himespetchi's sadness.

They convince him to make amends with Ikaritchi, who finally shows Mametchi his softer side.
