Wait!

#PhoneGuy, has a rotary phone head, and #PhoneDude has an iPhone head, and in that the icon is an orange, not an apple, and oranges are edgeless.
So we have one part, zero.

FNAF has 3 games, so that's three.

#FNAF, has 16 phone calls.

Multiply sixteen by three, and you get forty-eight.
Forty-eight divided by the nights of the first games and the two where Phone Dude is present(sixteen), is three.

Three plus that zero, is three.

a triangle has three sides...
