The Halliwells are finally on vacation, it's time to have some fun in New Orleans. But on the very first night Prue, Piper and Phoebe spent at the Big Jolly, Phoebe had a dream filled with a vision of a strange, frightening ritual under the full moon. Soon After this, Prue's new friend disappears during the full moon! And when the Charmed Ones try to find her, they find themselves immersed in the dark world of voodoo magic... the most powerful magic the sisters have ever seen. Horror in the Night The Bad Moon Rises. Piper saw a huge black snake rising from the flickering fire. “What kind of snake?” “she asked. “It looks like... that monster from my visions,” Phoebe answered. “That snake was going to eat that girl.” “It’s not a snake at all, it’s a loa - an evil spirit of voodoo,” Randy muttered. Meanwhile, the monster turned to them and aimed at them with its fiery eyes, huge poisonous teeth sticking out of its mouth. Piper had never seen such a vivid personification of evil before. “It noticed us!” - Yvonne screamed. “Rather, you must use your power if we want to escape!” Stepping out from the shadows, the three Halliwell sisters held hands and began to slowly move towards the loa. “The Power of Three!” - Piper shouted, encouraging the sisters, who squeezed her hands. - The Power of Three! - they answered her.
