Then Jaka Bandung led the Pengging troops to fight against the troops Prambanan, at that time the Kingdom of Prambanan was led by Raja Boko. His body was so tall that some people considered him to be a giant descendant.The giant king began his attack first, he sprinted forward, followed by the troops behind him. The Pengging Troops that scattered and tried to get up had no time to get ready ready to face the onslaught of opponents. With King Boko easily catching one by one Pengging army then thrown high into the air, of course the soldier died when it fell to the ground. Prambanan troops also With deliciously slaughtering the messy Pengging troops abysmally.
