Plastic Beach isn't the sort of place you'd expect ponies to be on. But Harmony is there, and has won a place in a certain singer's heart. But can 2D keep Harmony hidden from Murdoc? Will Cyborg start sticking up for herself? Will the Boogieman take Harmony? And what sort of mischief can a unicorn filly get into? So many questions, and thankfully, plenty of answers too.
