Tamagotchi!

Mametchi and friends participate in a big race hosted by Tamagotchi Town's idol, Lovelin to win a Lovelin themed game console. But to get to the end, they have to go through many obstacles such as hamburger building, giant pencil stacking, and obstacle courses!

Lovelitchi transfers into Tamagotchi School and Mametchi's class welcomes her, but she leaves early to work her idol job at TAMAX TV. After school, Mametchi and friends realize that Lovelitchi left before she knew about today's homework so Mametchi builds a device to track her down. They go all over town following the device which touches upon Lovelitchi's recent locations.

Mametchi's class takes a field trip to TAMAX TV where they run into Lovelin who invites them to watch her act in a cooking show. She ends up fainting from working too hard at so many shows and it's up to Mametchi and friends to take her spot! The Spacey Brothers encounter a tough looking tamagotchi and follow them around fearing that they too, want to take over the world.

Mametchi, Memetchi, and Kuchipatchi decide to go to the Forest of Truth in search of "The Kuchipatchi of Truth". They finally find it, but they get sucked into a strong bright light! Lovelin notices that a mysterious email has arrived on her cell phone "Telelin". Wanting to know the meaning of it and its sender, she tries to consult Mametchi and the others.

Mametchi and the others get sent back in time to the era of the first tamagotchis! In this era, tamagotchis are suffering from huge attacking plants. Determined to help everyone, Mametchi builds a mecha to defeat them. Lovelitchi gets sent back in time to the same place as Mametchi and the others. Her cell phone "Telelin" starts talking, surprising her. They both join Mametchi to save the tamagotchis in peril.

Telelin wants to go to TAMAX-TV to watch Lovelitchi act. Lovelitchi agrees, but Telelin disrupts the filming. Telelin promises not to interrupt again, but when Lovelitchi is in danger, Telelin has no choice but to take action. Lovelitchi takes Telelin to Tamagotchi School to introduce her to her friends, but she realizes Telelin is missing. While the others look for her, Telelin explores the school and causes events which lead some Tamagotchis to think that there is a ghost in the school.
