Im a fellow friend of the creator here, just to clarify some things, that is what we call the "lineup center". the lineup center is where current/returning props are shown on custom themes, these arent really ideas. at this time he only makes props who have their video released. quick edit, the creator is JohnTRoblo.
@Zer0isez my guess is no, ive worked with him before, (not really..) hes kind of a one man team, he doesnt usually make themes until real photos have been shown, example being flagship or window leaks, he primarily works on the animatronics before the themes. he doesnt even let me help him lol.
It could have 4 part of carnEVIL Because In 2010 They have a theme for the horror movie props So I guess they one for each prop Like they little theme So Monty could come back because they is a other animal prop And the clowns could be in the front Then the graveyard if could be the same like this in the vid
