The episode begins with the Straw Hat Pirates docked at a small island called Long Ring Long Land. The crew is in high spirits after their adventures in Alabasta, but they are also eager to explore this new location. As they disembark, they notice a peculiar giant shell on the beach, which piques their curiosity. Usopp, always the dreamer and storyteller, is particularly fascinated by the shell and begins to imagine its potential.

As the crew investigates the shell, they are approached by a local named Kuro, who is a member of the island's inhabitants known as the Longarm Tribe. Kuro explains that the shell is known as the "Eight-Foot Shell" and is said to have magical properties. He shares a legend about how it can bloom flowers and bring good fortune, which captures Usopp's imagination. Inspired by the tale, Usopp decides that he wants to make the shell bloom, believing it will prove his worth as a sharpshooter and a man.

The crew, particularly Luffy and Zoro, encourages Usopp to pursue this goal, but they also express skepticism about the shell's magical abilities. Undeterred, Usopp gathers materials and begins to work on a plan to make the shell bloom. He is determined to show everyone that he can achieve something great, despite his insecurities and past failures. His internal struggle is evident as he grapples with feelings of inadequacy compared to his crewmates.

As Usopp works on his project, the crew encounters a group of pirates led by a man named Captain Banchina. The pirates are notorious for causing trouble on the island, and they quickly confront the Straw Hats. A confrontation ensues, with the pirates attempting to intimidate the crew. Usopp, feeling the pressure to prove himself, steps forward to defend his friends, despite his fear.

The fight breaks out, and Usopp uses his slingshot and various gadgets to fend off the pirates. He shows surprising bravery, but his attacks are initially ineffective against the more experienced pirates. The crew rallies around him, providing support and encouragement. Luffy and Zoro take on the bulk of the fighting, showcasing their strength and skills, while Usopp continues to try to make his mark.

During the battle, Usopp has a moment of clarity where he realizes that he must believe in himself to truly succeed. He recalls the stories he has told and the dreams he has shared with his crewmates. This realization fuels his determination, and he devises a new plan to use the Eight-Foot Shell as a weapon against the pirates. He combines his creativity with his sharpshooting skills, aiming to make the shell bloom as a distraction.

As Usopp executes his plan, he successfully hits the shell, causing it to release a burst of colorful flowers. The unexpected explosion of color catches the pirates off guard, momentarily stunning them. This allows the Straw Hats to gain the upper hand in the fight. Usopp's confidence grows as he sees the impact of his actions, and he begins to feel like a true member of the crew.

With the pirates distracted, Luffy and Zoro take advantage of the situation and defeat Captain Banchina and his crew. The battle concludes with the Straw Hats victorious, and Usopp's bravery is recognized by his friends.
