In the Mushroom Kingdom, there were two sisters. Each one in line to the throne of Mushroom Castle. The beautiful, mature, and kind older sister, Princess Toadstool. And the competitive, multi-talented, and secretly jealous younger sister, Princess Peach. Toadstool did everything in her power to make the Mushroom Kingdom a prosperous and beautiful place to be. Even after a few kidnappings by the evil King Bowser Koopa, which followed up through by being saved by Mario saving her, she still managed to keep improving the kingdom everyday to the point of making it a world for everyone to live happily. However, her sister, Peach did nothing of the sort. All she loved to do was to win in competitions of many kinds. And did everything in her power to win even to the point of manipulating everything to her spoiled will. She competed in sports, kart races, party boards, and many more. And she almost always managed to either win or drive the others mad to the point of giving up. She had a nack for getting what she wanted. Though, there were few things that she couldn't have and those were the things that she wanted the most. And she was willing to kill in order to obtain them.
Obviously, the one with the throne is the one with the power. And Toadstool was the one in the throne, so she was the one everyone looked up to. Peach saw how much love and admiration Toadstool was getting being the active princess in the Mushroom Kingdom. And she wanted it. And when she tried to take it from her sister, Toadstool only said...
Toadstool: Dearest little sister. You have so much potential that could be put to good use for the Kingdom. But I am the one given the responsibility. Please, just be patient. If something were to happen to me, you would be the one to take my place. But that would not be until I pass away. In the meantime, why not have fun and play some more of your games? Your very well-skilled and talented at those games that you love to play. Also, you are the only one out of the two of us that can play, afterall.
Peach took what her sister said to heart. Perhaps a bit too much. But she still wasn't satisfied with those words. She didn't want to wait. But that wasn't the only thing that Peach wanted from her sister. Toadstool was seen as a beautiful maiden among the common folk while Peach was just seen as a cute little girl. Peach wasn't satisfied with that. She wanted to be pretty, not cute. She wanted her sister's looks. She wanted.... her face.
One day, Peach comes up with a plan to finally take what she wanted. She goes up to her sister and says...
Peach: Big sister! I'm going to Forever Forest!
Toadstool: Why on earth would you want to go there?
Peach: Because I wanna pick the glowing mushrooms there! They aren't poisonous, so I think I could make a cake with a few of them.
Toadstool: You are NOT going into that forest, Peach! You're far too young! You could get lost in there! And if you get lost in Forever Forest, you may never find your way out!
Peach: But I REALLY wanna go out there! C'mon, Toadstool! PLEASE?!
Toadstool:.....*Sigh* Very well. I'll accompany you so you won't get lost. I just hope that this cake your making is going to be as good as all your others have been.
Peach and Toadstool walk out of the castle and over the bridge at Southern Toad Town where the guard of Forever Forest stands. Toadstool assures the guard that they are only going to be in there for a minute to pick the mushrooms, then leave. The guard lets them in.
Once inside, Peach leads Toadstool deep into the forest. Deeper than where the mushrooms are. Toadstool quickly realizes that they are both not going in the right direction. Peach is however pressing forward. They both come up to a lone tree in the middle of one of the rings with the 4 paths. Toadstool is confused.
Toadstool: Um... Peach. Why are we here? Weren't the glowing mushrooms that way?
Peach: Oh... I saw some over there. Near that tree. Could you please stand over there?
Toadstool: Oh, you mean right here? What is here?
The tree comes to life and extends its branches. It opens its eyes and crooked mouth and proceeds to grab Toadstool with its branches.
Toadstool: Huh? AH! AAAAAAAAAAAAAAAAAH!!!!!!!!! Let me down! LET GO OF ME!!! PEACH! Quickly! DO SOMETHING! GET THE CLIPPERS!
Peach just stands there looking downward. Starting to chuckle. She slowly looks up to Toadstool with a big grin and says...
Peach: Just looking at you and listening to you scream for help is starting to make me laugh! I always wanted your face. I always wanted your voice! *Tilts her head slightly with that same grin* Big sister. Can I have it, please?
Toadstool: Huh?! What are you talking ab- UGH! *She sees that her left arm has just been torn off* AAAAAAAAAAAAAAAAAAAAAAHHAAAAAAAAAAAAAAA!!!!!!!
The tree begins to cackle and laugh as Toadstool's blood starts leaving her body in a crimson red mess.
Peach: You always got all the looks. *The tree tears off Toadstool's right leg followed by Toadstool screaming* You even got the throne. *Off comes the left leg and the tree now covers Toadstool's mouth. Her screams are now muffled* And everyone looked up to you. *The right arm now. Toadstool's organs are now beginning to droop and her blood is pouring out* And now.... *The tree lowers Toadstool to Peach. Peach moves in closely and whispers* They're....All....MINE!!! *The branch that covers her mouth impales her through the throat*
Peach then drops to her knees to the now dead Toadstool on the ground. She takes out a single spoon that she hid in her pocket and starts taking out the inner parts of her sister's remains and puts them all in her flesh. She takes a butcher knife and a potato peeler that she stole from Tayce T. to slice and peel the skin off her. She tries to stay quiet on the off chance that someone may be around to hear her. She takes the remaining flesh and innards and puts them back together and switches dresses with her. She takes her sister's skin and puts it on herself. She slips the legs on like stockings and the arms on like gloves. And wears her sister's torso like a chestplate and her face as a mask. Though she could not do anything about the hair, she had a plan for that. She calls upon Kamek to assist her. She had planned that from the start. She had Kamek put her completely back together and swap the two's hair colors. Peach's darker hair turns shining golden while Toadstool's turned from blonde to a dark brown. Her next order for Kamek was to have him completely fuse her sister's skin onto her. He asked why they go through with all this, and Peach reminded him...
Peach: I told you. If you don't help me fully, Kamek! I will do the same thing to you!
Kamek's face turns blue and he quickly complies to her demands. Toadstool's skin now magically fuses with Peach's. Toadstool's face is now permenantly Peach's new face. She grows slightly taller and the blood disappears. As if nothing happened. Kamek disappears into the shadows and flies away. Peach now picks up the intact but skinned corpse of her sister and waits until night falls. When everyone is asleep, she takes her sister's body out of the forest and sneaks it passed the sleeping guard, over the bridge, and up the road. She carries the body over to the newly formed Toad Town Gardens, and proceeds to bury her 6 feet into the garden. She takes the knife and cuts her apart again and puts the left and right legs in the southern most corners of the garden and the left and right arms in the northern most parts. And the head and torso in the very center with the arch over her. She quickly and thoroughly covers the holes with dirt. She then goes to her knees once again and starts crying. But then slowly starts laughing.
Princess Toadstool is dead and becomes the fertile soil for Toad Town Gardens and Flower Fields. Eventually, flowers have grown in the Toad Town Gardens, died, and have left behind Magical Seeds for one day to have flowers grow again. In the resting place of the late fair Princess Toadstool.
Years passed and noone suspected a thing. Peach knew this since the kingdom is full of mushroom-brained idiots. They didn't suspect that one of the sisters have gone missing. Just as Peach wanted it. As the years went on, everyone even forgot Toadstool's existance. Even Peach didn't even remember her own sister. She moved on to bend the kingdom to her will. And there is no stopping her.
All hail Princess Peach. Ruler of the Mushroom Kingdom.
