--Heyy, don't mind the skid code.
--If it errors, it's because you tried to copy and paste this without making an effort so it can work. Don't come crying to me if it's broken.
--Otherwise, dm scar#8268 on discord or Fifkee on roblox if you have any questions, or if I missed a function that bonnie has.
--Remade the script, was extremely buggy. It's stable now.
--NOTE: Bonnie, Chica, Toy Bonnie, Toy Chica, Balloon Boy, and Mangle go in the vents. NOBODY ELSE.
--holy heck thats a lot of people.
