I got it, the only possibly true explanation, while Cyrus was trapped in the Distortion world he was traveling around looking answer to why his plans failed ect.., when he managed to find another portal leading to the real world, suddenly a Bidoof jumps through it, Cyrus kicks the Bidoof back through and walks away, not ready to leave yet, then the Bidoof jumps back though along with a lot more Bidoof's, they attack Cyrus and eat him, thus ending his threat to the world.
See a perfectly good explanation to what happened to Cyrus and a use for the otherwise unneeded Bidoof's, result.
