whats inside the box?

The milk

Fnaf toys of the animatronics
Hospital band
Broken picture frame of the afton family

i think the box contains the body of C.C and that William Afton put him there to 'put him back together'.

Hmm maybe

exotic butters

Mik

my happiness

probably a golden freddy mask indicating cassidy

I've always been wondering what is inside the box

C.C toys or People
