I just noticed how Tammy and Bonnie are kind of the same.
Tammy witnesses her friends' demise including Duckie and becomes the most emotional like how Bonnie is the most emotional during the Fazbear Massacre story.
Tammy has also faced a certain rabbit character known as the Pumpkin Rabbit while Bonnie faces off Springtrap on night one.
The only difference is Bonnie survives but Tammy dies and becomes another one of the Pumpkin Rabbit's pawns.
The major similarity is that they lost some people VERY close to them. Tammy lost her best friend Duckie and her love interest Jessie in just two kills while Bonnie loses Foxy his best friend and Chica who is his love interest.
