Oh Celestia No - Oh God No, but Shadow Dash and Blackout Dash sing it(FNF: Mario's Madness V2)

"After reaching the vacant castle deep in Everfree Forest, Shadow proceeds to enter and find Nightmare Moon's "secrect weapon", so he can put a stop to her plans once more. But then, it turns out to be... his own twin brother, Blackout Dash...?! Will Shadow be able to reach out to his brother, or is it already too late to save him...?"
