I used to be super into FNAF and I drew Mangle *all* the time. (some long time watchers probably recall that)
I kinda fell out of it after FNAF3. I watched a no commentary play through of Sister Location and it was good to me. Ballora and Baby are cute, but Mangle/Funtime Foxy will always have a special place in my heart.

I believe this was the first time I drew Mangle, if not one of the very first pieces I did
