Regrets of a Hero

When Mario goes on quests to save Peach, the Yoshis cheerfully help him, slurping up enemies and getting him over cliffs. But sometimes, Mario sacrifices them to keep going. So one day, he is going to save Peach when he finds yet another Yoshi and has them flutter-jump over a cliff. Mario then jumps off of the Yoshi and lands on the other side of the cliff unharmed. However, for the first time, he looks back, and the expression that he sees on that Yoshi's face when he does just that possibly changes him forever. But first, he and Peach have to escape from Bowser's castle after he goes big and captures them, Luigi, Daisy, and Toadsworth.
