After clearing Bad-Mouth Sugoroku, Yuichi and Tenji find themselves trapped in a dark cave for three days. During their isolation, Tenji makes the shocking revelation that he had already experienced a Tomodachi Game in the past. Meanwhile, a team of new opponents lies in wait outside, anxious to challenge the two partners to a grueling third game.
We thought we knew each other, 
but we're basically strangers.
.ظننّا أنّنا نعرف بعضنا، لكنّنا غريبان
Wir glaubten, uns zu kennen,
und hatten doch null Ahnung.
Creemos que nos conocemos,
pero no es así.
Creemos que nos conocemos,
pero no es así.
On savait rien les uns des autres,
en vérité.
Pensiamo di conoscerci l'un l'altro,
ma in pratica siamo dei perfetti sconosciuti.
Pensamos que conhecemos uns aos
outros, mas somos basicamente estranhos.
Мы думали, что знаем друг друга,
но куда там.
