Kikitchi is playing with brooms with Sabusabutchi, while Kumattatchi and Gourmetchi talk about fried chicken. Chamametchi, Akaspetchi, and Pipospetchi then remind everyone in class that everybody must clean up the classroom. Everybody realizes and starts cleaning. Then, Chamametchi looks behind her and sees an octopus-like Tamagotchi cleaning. Chamametchi then remembers something about her.
In a flashback, the math teacher Mr. Dentaku presents the class with a math problem: 10 + 24 = ?. Nobody answers. He asks Atsuatsutchi and Sabusabutchi, but they do not know. As the teacher thinks of another person offering them to answer for the class, the octopus-like Tamagotchi raises her hand and answers 34. The teacher is impressed that she answered correctly. It was later revealed that the name of that octopus-like Tamagotchi is Octodogtchi, according to the teacher.
After the flashback, Chamametchi comments that Octodogtchi is quiet, but very focused on her studies, and she gets good grades. Kikitchi comes up to Chamametchi and asks why she is just standing there. She says that she wants to make friends with Octodogtchi. Kikitchi is briefly surprised, then he considers it, and he adds that Octodogtchi is shy and doesn't talk to anyone.
The school day ends, and everybody leaves school. Chamametchi stops for a moment and looks back in her classroom. She sees Octodogtchi sitting alone and carrying something. Chamametchi goes up to try talking to her. As she approaches her, Octodogtchi gets spooked at first. Chamametchi pauses for a short moment, then tries to start a conversation by saying hi. Unfortunately, Octodogtchi runs out of the classroom. Chamametchi tries to keep up with her. The two girls pass by Kikitchi in the hallway, who wonders what's going on. The chase stops at Principal Mimizu's statue, where Chamametchi stops to take a breath, and loses sight of Octodogtchi.
Kikitchi catches up to Chamametchi and says that this proves that Octodogtchi won't talk to anybody. But Chamametchi is determined to be friends with Octodogtchi. Mametchi, Memetchi and Kuchipatchi, come up to them and show them two green papers with triangle patterns. Mametchi asks if they belong to either Chamametchi or Kikitchi. The two said it wasn't theirs. Memetchi wonders what the papers are. Everyone thinks about it. Then Kuchipatchi takes it and claims it's a musical instrument, where he strokes the triangle patterns on top of it. Memetchi takes it and says it's a crown. She puts it on Kuchipatchi's head and describes him a "Tropical Island King". Kikitchi then thought that a king came to Tamagotchi School and dropped it by accident. Kuchipatchi said if it were true, people would argue about it. Mametchi then thinks it's a ninja camouflage tool, like the kind used by Gozarutchi.
Then Chamametchi thinks it's "typical stuff" from lunchboxes. Everyone else says that she means "bento grass", a type of decorative lunch ornament. Kuchipatchi notes that the size of bento grass is big for a regular lunch box, then he adds the food in the lunchbox must be big. The gang starts to imagine a lunch box which is the size of themselves. Kikitchi is big as a broccoli, Chamametchi is big as a cherry tomato, Kuchipatchi is shaped like meatloaf, Memetchi could look like an apple slice, and Mametchi looks like a piece of fried chicken.
Mametchi suggests that the gang should figure out who owns the bento grass. Chamametchi thinks the grass belongs to Octodogtchi. Memetchi suggests they could ask her. However, Chamametchi said she was uncertain. They are all still unsure about it.
The next day at Chamametchi's classroom, Chamametchi takes the bento grass out of her desk and asks Octodogtchi if it is hers. Octodogtchi briefly blushes, and unfortunately, she runs away again. Chamametchi starts following her. Octodogtchi briefly stops to look at Chamametchi, and then she says that the grass belongs to her. Octodogtchi blushes intensely, and then continues to run away from her. She dashes out of the school. Mametchi and Memetchi are hiding behind the statue of Principal Mimizu and see Octodogtchi. They and Kuchipatchi and Kikitchi try to stop her in order to ask her, but Octodogtchi goes around them. Kikitchi then goes ahead to pursue her. Chamametchi meets up with the rest of them and tells of her attempt to talk to Octodogtchi. Kuchipatchi has doubts if the grass did belong to her. Mametchi tells the gang that they should follow Octodogtchi. As they run after Octodogtchi, Memetchi remarks that it wouldn't be so annoying if they weren't chasing Octodogtchi. Then Kuchipatchi hopes that Kikitchi doesn't lose her.
Octodogtchi stops in front of a studio and goes inside. Kikitchi was hiding behind a large drinking cup sculpture and saw her. Then the rest of the gang come up to him, and he points out that the studio is Octodogtchi's house. The gang watches Octodogtchi through a window. Octodogtchi talks to herself that she doesn't want to be shy. Chamametchi tries listening her more, but she accidentally falls through the window, causing Octodogtchi to look at her.
As they meet eye to eye, Chamametchi tells Octodogtchi that she has been looking for her. Then she shows her the bento grass and asks if it is hers. Octodogtchi finally opens up to her, and says that she lost it. The two walk up to each other, then Chamametchi gives the grass to Octodogtchi. Chamametchi wants to know what the grass is. Octodogtchi becomes embarrassed again, turning bright red and then hiding behind a giant sandwich-like piece of furniture. Then she carefully peeks out to look at Chamametchi. Chamametchi asks if she is okay.
The gang leaves the studio. Chamametchi becomes unsure if she said anything that hurt Octodogtchi's feelings. The gang cheered her up by saying that she managed to give Octodogtchi the bento grass back. Then Mametchi suggests she should try talking to Octodogtchi tomorrow to see if she has changed. Chamametchi agrees. As the gang walk away, Octodogtchi watches them from her window nervously. Then she looks at her bento grass.
The next day in Chamametchi's classroom, Octodogtchi enters the room and sees Chamametchi. In spite of her shyness, she walks up to her and says thanks. Octodogtchi starts to talk about the bento grass, but then she tells Chamametchi to come to TAMAX-TV. Chamametchi wonders about it, but then Octodogtchi becomes nervous and runs away again. Kikitchi saw it and was disappointed that what Chamametchi said made Octodogtchi run away. Chamametchi is still uncertain.
Mametchi, Memetchi, Kuchipatchi, Chamametchi, and Kikitchi arrive near the TAMAX-TV broadcasting studio. Then they see a sign that says a dance contest is being held. They go to the stage where the contest is. Two Tamagotchis mention that the next contestant is a girl known for her spectacular dance that means a lot to her. The gang asks the two to ask who the girl is. Then a host announces the show is about to start.
On stage, the two hosts introduce the next dancer: Octodogtchi. This surprises everyone in the group. Octodogtchi then begins to dance. She starts by hopping around, then she begins spinning. Chamametchi realizes as she watches that the green thing that she gave back to Octodogtchi was actually her costume. As the show continues, Octodogtchi leap around. Chamametchi and Kikitchi are amazed. Then Octodogtchi noticed the gang. Regardless, she continues dancing; she jump spins, sways, and cartwheels. Then she finished with a big jump spin. The audience applauded, including the gang.
Octodogtchi wins the contest and is presented with a trophy. Chamametchi congratulates Octodogtchi for getting first place in the competition. Octodogtchi explains that she needed her costume to dance. Then she was thankful for helping her doing her best in the contest. Mametchi then said that the two have now became good Tama-Friends. The rest of the gang agrees. Octodogtchi and Chamametchi smile and are both happy with each other.
Let's Celebrate! Tama-Beans Festival
Let's Celebrate! Tama-Beans Festival (ままーめままめ! マーメの日 Mama-me mamame! Māme no hi) is part 2 of episode 17 of Tamagotchi!. It aired on February 1, 2010. The episode is written by Michiko Yokote.
Papamametchi and Mamametchi are carefully picking sorting pieces of food when they are interrupted by Chamametchi and Mametchi coming inside. Mametchi notices what they are now called, Tama-beans, meaning that the Tama-beans festival is on. The parents say that the festival is an important ceremony and must be careful. They explain that if they are able to make an exact amount of Tama-beans collected, it can expel the evil in their house. But a single mistake, "will cause a terrible thing to happen". Afterwards, the parents asked their kids to change clothes while they begin their ceremony.
After Mametchi puts on his ceremony clothes, Chamametchi ask his brother about the evil things that will happen after making a mistake with the Tama-beans. But Mametchi is unsure what will happen and says that they must not take it as a joke. Once the family gathers together, Papamametchi and Mamametchi carefully analyze the Tama-beans collected. Papamametchi recieves 44 beans, Mamametchi gets 25 beans, Mametchi has 52 beans, and Chamametchi gets 16 beans. Then, the family begins performing the spell. The spell for the beans consists of spinning around, chanting the name, and throwing the beans at the same time. They've performed it around the parts of the house. And comes to a close after pleading to expel the negative energies and falling back flat to the floor.
Finished with the ceremony, everybody now has to pick up the Tama-beans. Hapihapitchi asks why, and Papamametchi replies that the beans have absorbed the negative energies and should be put away. The families begin to pick up all the beans, counting up to the limit of the beans they would get at first. As Chamametchi, Mamametchi, and Papamametchi finished, Mametchi still needs to finish picking up. As he tried reaching out to the beans near the books, Hapihapitchi assists by giving a bean to him. After collecting the last two beans he spotted, he concludes that he got all the beans. Unfortunately, there is one bean hiding behind a stack of books.
Despite the missing bean, Papamametchi says the family managed to get past the ceremony. And everyone can relax. One week later, at nighttime, the missing bean begins to sprout. And then grows at an alarming rate. It toppled Mametchi's bed over, waking him up. He became surprised when there's a tree growing out of his room.
At morning, the neighbors are at the scene and Lovelin begins documenting on the grown tree. Interviewing with Papamametchi, he says he's working in the laboratory to investigate the tree and he is aware that the tree will continue to grow. Mametchi seems to understand the consequences of leaving a bean. Mamametchi double-checks if they are sure of collecting all the beans. Mametchi flashes back at the time when he's still picking up beans. Then suddenly realized he miscounted, and he must do something about it himself. He tries cutting down the tree using an axe, but bounces off. Then he uses his car-shovel to dig up the roots, but after a few hours, nothing happened.
Lovelin receives a notice. She read that the tree has grow so much that Tamagotchi Planet is now having a itch. It is behind the planet and its stubby arms couldn't reach it. Mametchi tries to think, as he dramatizes that the tree will cover the entire planet. In shock, he falls down. Lovelin reports that nobody knows how big the tree will grow and the investigation on it is still ongoing.
Then, Lovelin suddenly sees flowers at the top of the tree. But then the petals have fallen off. The remainder of the flower then blooms into big square beans. And the tree begins to wilt. It was revealed that the life of the tree is a day. At the next event, a square bean popped, revealing a shower of Tama-beans. But it appears to be a different kind of bean, as it has a sweet aroma of a fruit. A pedestrian takes a bite out of it and seems delighted of the flavor. Lovelin eats it and liked it too. This followed up with pedestrians crossing the fence to eat the beans. Mametchi decided to try for himself, and liked it too. Then the remaining growing beans pop, revealing tons of edible Tama-beans, which causes a pile up of the beans.
After the shower stopped, Lovelin states that the shower was only in Tamagotchi Town, thus the planet is completely safe. Then, everyone leaves the Mame Family alone at their house. Mametchi says he doubts anything can get worse. But his parents say it was only the beginning of the problem of the pile of beans, leaving the kids in question.
At morning, it appears the Mame Family are trying to eat all the beans before they can sprout in a week. They had a ton of beans gathered left, including the ones outside, much to Mametchi's dismay.
- The Tama-Beans festival is based on a real-life Japanese festival known as "setsubun" (known as Bean-Throwing Festival in English translation).
