Secret of the Village Underside

Secret of the Village Underside is the fifth episode of Pianta Village in Super Mario Sunshine. The episode's objective is to complete a secret course accessed under the village.

In order to access the secret course, the player needs to hatch the Yoshi found at the entrance of the village. Near the spa, there is a tree that grows every fruit in the game aside from peppers. By taking the fruit Yoshi craves to him, the player can ride him onto the mushroom platforms underneath the village. At the end of the mushroom platforms is a forcefield that can be destroyed by spraying it with Yoshi's juice, revealing the entrance to the secret course. As usual, Shadow Mario will appear to take F.L.U.D.D. away during the player's first visit.

The Secret of the Village Underside is made up of several platforms, with special Piantas known as "Chucksters" as the primary means of traveling between them. Talking to a Chuckster will have them throw Mario behind them a set distance, either horizontally or vertically. The player can adjust the angle of the throw by talking to a Chuckster from a certain position. The first Chuckster the player meets serves as an example and the second Chuckster can help the player reach a 1-Up Mushroom. The third Chuckster will throw Mario across the gap on to the next platform. The next two Chucksters move back and forth and have different strengths; the bigger one is stronger and the little one is weaker. The next Chuckster will throw Mario upward to the above platform with many Strollin' Stus spawning on it. Behind the platform is a tightrope that leads to a platform with a flaming Pianta the player can only interact with on their return visits. The Chuckster on the platform with the Strollin' Stus will throw Mario to the next platform with a Chuckster circling the center ledge. Speaking to that Chuckster from the proper angle will have him throw Mario to a platform with either a 1-Up Mushroom or the Shine Sprite.

Red Coin Chucksters
Revisiting this course will allow the player to use F.L.U.D.D. and do a Red Coin challenge. Ground Pounding the Red Coin Switch will cause eight Red Coins to appear throughout the course and the player has to collect them all within a time limit of one minute and thirty seconds. Completing the task will reward the player with a Shine Sprite, but failing to do so will result in Mario losing a life and starting the challenge over. The locations of the Red Coins are:
 * High in the air above the second Chuckster.
 * In the third Chuckster's path.
 * Two are on the platform with the Strollin' Stus.
 * Above the tightrope behind the platform with the Strollin' Stus.
 * On the platform with the flaming Pianta.
 * The final two are on the platform with the circling Chuckster.
