Disco Apocalypse

Disco Apocalypse turns the Disco mutation into a challenge: a rift tears open the dance floor, and you have to survive every round standing on the right color to earn a chance at Disco. The other Disco weathers simply give fruit a small chance; this one asks you to perform.

The prize is the same x125 mutation, so the payoff is identical and what changes is the route, a mini-game instead of a passive roll. The wiki does not say how many rounds there are or how long each lasts, only that surviving all of them is the requirement, and it still describes the result as a chance rather than a guarantee.
