You watch closely as gill form on Manny's neck, while his brown hair became so long, that it stopped at the middle of his back, and his limbs became skinny as a woman's. Manny then developed an hourglass body shape, while his own body-hair fell off, and flew away, while his own butt inflated, becoming plump.
Manny's vocal-chords were altered, giving him the voice to sing like a mermaid, and two lumps grew on his chest, as they became E-Cup breasts to match the size of his butt. Manny has now become a woman. "Wow Manny, you look stunning when you're female," You comment. "You can call me Mandy now, Canden, and we're not done yet," Mandy explains. "There is one more thing you need to do to make me become a mermaid, and that's kissing me on the lips." You do what she instructed, and blue scales formed on her legs.
