Full change

A few minutes later, the egg cracked. It then broke apart and let its occupant out on the floor. Peach was completely changed. She still had her figure and size but now had some Bowser's features. This included his claws, scales, horns, tail and more.

Bowser loved how she turned out. "Great work, Kammy!"

Kammy did not expect it to work so well but went along as if she planned it. "Um...Of course, sir!"

Peach was shocked seeing herself as a Koopa. "What?! What happened?!" She was not sure where or what she was but then she felt something else looking at Bowser. Her new form somehow made her feel attracted to him. She blushed and walked up to him.

Bowser smirked figuring she was falling for him as they were now the same race. He wondered what to do next.
