After some deep delving into the depths of modern app stores, you can across a second-hand app store simply named, "The Magic App Store". Clicking on the description, you see:
"The store for magic apps with varying purposes, with transformation, reality alteration, and so much more! Fulfill any and all of your desires with the apps from the app store!"
Although shady-seeming, you couldn't see anything wrong with the store itself, and it was approved in the main app store, surprisningly enough. It wasn't raunchy in any way, and seemed genuine.
....
....Your curiosity got the better of you and you pressed [Download].
After a few minutes, a notification popped up, saying the app was downloaded. Without delay, you opened the store, and are greeted with a large catalog similarly odd and shady, but seemingly genuine, apps.
