Serene Stream (ながれおちる わきみず?) is the second main area in the Verdant Waterfront. It takes place inside a cave with several shallow streams of water that can carry Captain Olimar, his Blue Pikmin, or even enemies into different places.
The area takes place in a big cave, and is mainly made of waterfalls. The player starts right next to a waterfall, foreshadowing the theme of the area. Some steps further, Olimar meets some Blue Pikmin, and a Shearblug. After defeating this creature, the player will go down a waterfall, leading the protagonist deeper in the cavern. At the end of the stream, the player can use his jetpack to enter a small hole, which contains a Mockiwi and a vine leading to the Attitude Adjuster. After going down some waterfalls, a Mockiwi will exit an hole, and going down the same waterfall as Olimar. However, at the end of the waterfall stands a big stretch of water, causing the Mockiwi to drown. This underground lake is infested with Puckering Blinnows and Shearblugs. When heading to the left, the player can get access to a Sparklium flower, along with some Blue Pikmin. At the bottom to the stretch of water, there are dirt blocks, and one of them hiding an entrance to a doorway. On the other side, there are some Puckering Blinnows and a Crested Mockiwi. Olimar has to kill it in order to get the second treasure, the Unstrung Racket. When the player gets back in the main area, and takes the doorway to keep going in the area, they must head to the left (thus going against the tide) and go through a small hole in order to retrieve the last treasure, the Work-Life Imbalancer. Some time after this, the player will be, once again, chased by a Mockiwi in a stream. It doesn't last long, but right after this, there is a second waterfall with another Mockiwi to escape from. There are also some Sparrowheads on the way, making the trip harder. The waterfall ends in a lake, with the exit next to it.
