Heart takeover

Intro So in this world there’s a happy fun relaxing and entertaining park all pink and cute. But no one ever leaves or even wants to. But in a lesser known part of the park there was the creator a being who’s heart was taken out and became with the park being it and also having a body it could control unless the heart was destroyed. The park also emits a pink fog that makes people want to stay and maybe even forever. But recently some people wanting to save the people came to the park and went to the back. They fought the body it was using to no use but before the same vines that hold the heart took them one of them stabbed the heart destroying it and the body but the place remained and the people were sealed in a secret dungeon like area where the pink fog is inserted directly into them by vines. But the point is… you went in this park and the park needs a new host… someone people won’t notice if they disappear and can be controlled by the fog to head by the place. What will happen is you will be taken by huge vines that will take your body but first your heart will break out of your chest look more cartoonish shaped and then grow larger as the vine connect to it becoming like veins. You will be taken and as your heart becomes the parks new host your body will over time be in a vine cocoon that turns it into a physical form you can control but will look a bit like the last owners form. Add whatever lore you need and I kinda may have based it off of the new Cookie Run Kingdom update but modified.
