Herb, Mint and Lime at near the top, and encounter some aggressive monkeys at the top, which don't attack because of the others being part animal - and they're afraid. When Ranma and co turn up, the monkeys attack them. The Chiisuiton points out to where the Kaisuifuu, a big rock shaped by a kettle. Ranma, carrying the duck and pig run towards it, but are out-paced by Herb, Mint and Lime. An underground stream is connected to the rock-kettle, and Herb blasts off the end of the spout, which releases the water, and a small mettle kettle can be seen hanging inside the spout, which is heating the water.
Herb walks into the hot waterfall, and walks out a guy.
Ranma isn't surprised Herb was really a guy. Open Water Pot Herb does his soaring attack, which completely knocks out Ranma. He tells the pig and duck to the Kaisuifuu while Ranma deals with Herb. The rock holding the Kaisuifuu breaks apart, distracting Ranma, and Herb nails her. Herb is about to slice of Ranma's neck as the pig and duck chase after the Kaisuifuu.
