"Main Theme (Beta Mix) - Hey! Pikmin" is a high quality rip of the beta mix of "Main Theme" from Hey! Pikmin.
At 0:05, the advertised track is mashed-up with "The Yoshi Clan" from Yoshi's New Island, and then at 0:35, "Black Tar" from Xenoblade Chronicles X, specifically the line "We're stuck on a different planet".
This rip was originally published to GiIvaSunner on March 22, 2016, as "Main Theme - Pikmin". Following the GiIvaSunner Termination, it was reuploaded to SiIvaGunner with the same title on April 30, before being removed at an unknown date between February and April 2017. Following an announcement that Arzest, the developers of Yoshi's New Island, would also be developing Hey! Pikmin, the rip was reuploaded with its current title and thumbnail.
