Yup, I drew Mangle and Foxy as a pregnant couple, and yes, while Mangle is a girl so did I keep Foxy as a male. So yeah, mpreg.
Bonnie on the other hand finds it awkward to step in to see two animatronics somehow being pregnant, no matter what gender they are (and that's probably how a lot of people seeing this image will feel like. :P )
