Hello! your here bc you want to have a normal mangle and not a checkered purple and black one eh?
well i can tell you how! now your gonna have to download alot of mods.

what your gonna want to do is download every single pill pack the creators of made. ( dosent include TJOC I think but download just in case) i had this problem for a while but i downloaded every one and mangle is now fine! some people also complain about the fact of missing skin for all the pills and where to have pills all mods you need for the skins and the pill mod will be here!
