Mario & Luigi: Future DreamTown

Fun Fact: Originally, this was going to have Mametchi & Kutchipatchi with the Mario Bros. and the title for this was called “Mario & Luigi: Tamagotchi Friends” until the idea came up with the Tama twins who are exclusively in Japan. This was later merged to what you see here.

The Mario Bros has been jumping into some strange universes. Now they’ve jumped into the Tamagotchi universe (but in the future of DreamTown). The twins encounter the Mario Bros to work together whereas Bowser Jr. has stepped into a portal entering TamaTown. Meanwhile, Toad has also followed Bowser Jr. only to meet Mametchi’s & Kutchipatchi to find the Mario Bros.

I've known the Tamagotchi franchise in the 2010s by my cousins.
