Sheriff Mao Mao and his deputies/Friends Adorabat and Badgerclops have been defending Pure Heart Valley non-stop from Monsters and their collective nemesis's The Sky Pirats with great diligence...despite the damages. One day, while prepping for their monthly Vacation, Adorabat discovers a strange swirling portal in the nearby woods. After attempting and failing to secure it for safety reasons, the three are spat out into the land of Equestria. With no foreseeable way or time frame on how or when they'll get back, Mao Mao vows to assist in the defense of this magical land for as long as he is there while his new friends try to find them a way home. For a legendary hero never ignores the innocent, even if that hero can at times be a little over dramatic.
