Listen, in the beta release Foxy (aside Golden Freddy) is one of the original main cast (No Sugar, Kitty or Dug nor Shadow Lockjaw) to have his model articulated while the others are stiff (the A pose) and honestly I don't believe his early model is just the current one but without his spiky strands.

to this date i am still waiting for the release of that beta bro. it has been my obsession since I was 7 when I saw the trailer around my birthday despite being released 6 days prior to it. there are stuff that is cool and such from that version. although i doubt the testers got that version i still have that hope
