Forgive me if this was mentioned somewhere else because I could not find it on my busted laptop or phone but I have a theory that Oswald’s dad may have been the spring bonnie we see as the main antagonist.
Reason one: Oswalds dad gets nervous around the mention of freddies
Reason two: spring bonnie straight up replaces his dad and nobody else but oswald (and the cat) knows
If anyone has posted this before than I’m sorry for being stupid.
