One of the secret endings for the game can be triggered by drowning in the lake in the 4th Sub Tunnel. What happens may seem scary at first as Freddy falls down endlessly, but after two minutes, it shows this screen. Apparently, this ending has Scott and his two kids looking at a screen. The reason why that is heartwarming is when you realize FNAF World was meant to be the last game at the time, and it's a reflection on the death of the series and how it'll affect Scott and his family. What makes the ending even more special is that there are no textures for the screen you are seeing, it's made up of individual squares. So Scott making this ending so obscure shows it is very important to him.
When you really think about it, Chipper being playable means that he finally found a place where he can be accepted. Not only has he befriended the Animatronics, even after his attempt to kill them, but people seem to actually like him for once.
