Twilight and Trixie RPG

It was a bright day in Ponyville. At her castle, a bunch of background ponies stood in a line in front of Princess Celestia, moving horizontally to open up the way for some strange-looking biomechanical humanoids. Among the cyborgs stood a green man with a cloak, holding a present for Princess Celestia. As she opened the box, she was hit by pink gas and couldn't speak. She began to cry for a while before attempting to speak again, but instead of words emerged symbol swearing in a visible speech bubble. Then the symbols jumped out and exploded, scaring away all the background ponies as the man and cyborgs teleported away.

A while later, the blue unicorn Trixie went over to Twilight's house, panicking with an urgent message for her. Trixie walked up the stairs, not surprised to see lots of books scattered all over the house. "What an egghead Twilight is. She's so cooped up in reading, she can't even put her books away properly?!?" Trixie heard Twilight humming the MLP: FiM opening song in the shower upon reaching the upper floor. One of the same cyborgs that appeared in Princess Celestia's castle opened the door, ready to bag Twilight. Trixie yelled "AVADA KEDAVRA" and shot him dead with a green bolt. The cyborg exploded.

Twilight asked Trixie not to disturb her while she was showering, but Trixie reminded her that she doesn't wear clothes.

Twilight replied, "Neither do ponies in general. Why did you interrupt my shower?"

Trixie explained that showers are like a GPS for bad guys, and that cyborgs like the one she just shot down had stolen Princess Celestia's voice, replacing it with a literally explosive one. Twilight, ready to fix this problem, turned off the shower, and dried off with a towel.

Twilight asked Trixie if there was a spell to stop this, but no, the original voice has to be retrieved for it to work. And as the two ponies set out to retrieve Celestia's voice, they met another of the strange cyborgs. He raised an arm cannon, and they prepared to fight him with the Mario & Luigi battle system.
