A whole new 3rd Mode in FNaS: Fiercy Forces "Imagine It!".
Purpose? To even scare more the Protagonist.

Those who are starting at the beginning of a Night:
(Clones, Animatronics, Phantasms)

Good -> Evil -> Amok
(Example ~ In the case of: Clone Sonic "Tune-Up!")

Good -> Craze -> Loony
(Example ~ In the case of: Clone Mighty "Hunt-Up!")

Evil -> Amok -> Whim *Those who are already in Evil Mode*
(Example ~ In case of: Nightmare Sonic "Spooky-Up!")

In the Amok/Loony/Whim Mode, the Characters take on a different appearance, unnaturally changing the shapes of some of their body parts.

In case of Sonic "Tune-Up!", his quills even tide up and his smile turns insane.
His ornament "Tempo Tune" on his top hat changes to violet.
Of course his eyes take on for an aggressive color and more blood flows
from his eyes.
This mode is more menacing and unexpected even than the Evil Mode.

The Frenzied Characters literally thirsts for Silent's "The Player/Avatar" FEAR.
And for sure they want for some Bites! Caution is advised!
