I think not just Foxy, but ALL of the animatronics are good. First off, I think the children in the suites don't know they are dead. So I think they just want to play hide and seek or tag. Foxy thinks it's tag and Bonnie thinks it's hide and seek. Bonnie is eager to get to you quickly while Foxy literally RUNS to you. They don't know what else to do but scream because they are now robots. Foxy leans and try's to say "Tag your it!" and Bonnie when he jumps at you try's to say "I found you!".
Now here are some trailer images for FNAF 3 that I have discovered:
And this stuff I found on Scott's website:

UPDATE 1/27/2015:The trailer is NOW OUT!!!
Still no update on Scott's website, BUT I want to say something. It's not Golden Bonnie who is in the trailer. No no no! *Peppa Pig V. G. U. Voice* It's actually ALL of them! Let me explain,
Thirty years after Freddy Fazbear's Pizza closed it's doors, the events that took place there have become nothing more than a rumor and a childhood memory, but the owners of "Fazbear's Fright: The Horror Attraction" are determined to revive the legend and make the experience as authentic as possible for patrons, going to great lengths to find anything that might have survived decades of neglect and ruin.
At first there were only empty shells, a hand, a hook, an old paper-plate doll, but then a remarkable discovery was made...
The attraction now has one animatronic.
Token from the steam greenlight post.
My video about the FNAF 3 teaser on NC Video Center is about the only thing left. Toon in next time!
