Is Springtrap Bonnie?

[Cursedfirefox]

The reason I ask this is cause if you look at the face structures of all the animatronics they are all similar regardless of the version that they are, even if you compare Freddy and Fredbear. But when it comes to Springtrap and Bonnie they look different. Everyone just assumed it was Bonnie because of the ears. When you look at Springtrap he looks more like a dog then he does a rabbit?

For Example:
Dog pic [vignette.wikia.nocookie.net]

Shows the floppy ears and all. its not until much later in the series does Springtrap get the split down the middle of his muzzle where his nose is. Not even plushtrap has the split.

Springtrap is Spring Bonnie, a springlocked animatronic suit that was made alongside Fredbear (now Golden Freddy) before Freddy, Bonnie, Chica and Foxy were made.
