On October 28th, 2017, the official Nintendo LINE account published an audio file titled “Jump Up, Super Star! Short Version Free Download”. The audio was a 47-second long sample of the background track of the “Jump Up, Super Star!” song from Super Mario Odyssey, with pitch-shifted Toad sound effects overlaid on top of it to resemble singing. The account then revealed that the song was supposed to be sung by Kinopio-kun, the green Toad mascot of the account, and posted a picture of Kinopio-kun dressed as Pauline (seen as the album art on this post). Note that the Nintendo LINE account is operated directly by Nintendo of Japan. Main Blog | Twitter | Patreon | Store | Source
