"Mamushi (Remix)" is a digital collaboration between Megan Thee Stallion and all nine members of TWICE, released October 25, 2024 as track 7 on MEGAN: ACT II — the deluxe reissue of Megan's third studio album. The original "Mamushi" featured Japanese rapper Yuki Chiba and went viral via TikTok before being serviced to radio; for the remix, TWICE replaced Chiba's verse, rapping and singing in English with lyrics that reference the group's own milestones — selling out SoFi Stadium, winning music show trophies, and name-dropping "One Spark." The collaboration arrived with no physical release and no TWICE-branded collectibles, making it a purely digital entry in the discography. For era-completionist collectors, the only physical artifact associated with this period is MEGAN: ACT II itself on CD or vinyl, released under Hot Girl Productions/Warner Music Group.
