Manta Rays, Taekwondo and Holi

Ed Petrie and his friends go on an adventure to find the most unusual places in Asia. This time they swim with manta rays in Indonesia, find a golden toilet block attached to a contemporary art exhibit called The White Temple in Thailand, visit a town totally devoted to taekwondo in South Korea, discover the world's biggest single site of dinosaur remains in China and get ridiculously messy at Holi, the Festival of Colours in India.
