I'm guessing 2 things may have happended to Donut:

1.  He may have missed the ship the Reds and Blues took to get back to Blood Gulch, maybe due to his habit of "organizing and doing something non-masculine."

2.  He may have taken a wrong turn on the Mongoose he was driving, and may have ended up in Valhalla.
