If you never grew up on a small island, watch this. If you did, watch this. Amazingly inventive and funny, full of cameos from the likes of David Tennant and Harry Hill. Perfectly pitched and balanced, with an excellent cast, the residents of the island of Jinsy are definitely act like inmates of an asylum, overseen on the behalf of "The Great He" by Arbiter Mavern and his ever faithful team of dripping, myopic and cleverer assistants. Whilst this may appear simple, it is anything other than that. If it is an asylum, the inmates have definitely taken over and they have a lot to sing about. So, daily greet and sing sing sing.
