This was the bizarre moment tourists were confronted with a family of ''ewok-like troll monkeys'' playing music on a Thai island.<br /><br />The creatures were seen sheltering under the rocks in Railay Bay in Krabi, Thailand, as bemused holidaymakers passed by a longboat and others in kayaks.<br /><br />A hypnotic ''cacophonic ritual'' was playing across the water. <br /><br />However, despite the almost alien-like appearance, the monkeys were actually performance actors and the sound was coming from travelling vocalist Tori Wranes who had staged the bizarre scene with local acting group Thailand Biennale.<br /><br />Onlooker Jemayel Khawaja, who recorded the video, said: ''So we were kayaking around Railay Bay in Thailand, turned a corner towards a cave, and found ourselves confronted with perhaps the most surreal and bizarre situation I've ever experienced - Ewok-like troll creatures engaged in some cacophonic ritual in the water. <br /><br />''It went on for like 30 minutes! What on earth is going on here?''
