Easter Eggs are hidden features within the game. They have a very low chance of appearing, although many of them don't trigger anything.

Lumberbot 5.0 on water tower Edit
A Lone Lumberbot 5.0 can be seen rarely on the water tower near Chipper's house, starring at the player. This easter egg has no effect. Chipper's Revenge from FNaF World may be a reference to this due to them looking similar and that FNaF World was made after Chipper & Sons Lumber Co.
