Sheik fights her changes and helps Rauru save the day.

Thoughts were filling Sheik's head, and they were, like, really nice thoughts too. Like, why not help Tiff and Impa? Because, like, it would be bad, right? Nuh uh! Isn't bein a bimbo fun? I guess, but, like, what about Ganondorf and stuff? We can totally make him a hot bimbo too~!

No. Came a sharp, clear voice from inside Sheik, from inside Zelda's mind. This has gone too far. With a hard expression on her face, Sheik pushed Tiff away from her, and before the bimbo could make a complaint Sheik sprinted over to Impa and threw herself into a legs-first slide aimed at the sage's feet. Without ever seeing it coming, the top-heavy Sheikah fell to the ground, her magic disrupted, and Rauru's anti-bimbo spell filled the air around them, shrinking everyone's chests and deblonding their hair.
