With Usopp now in the crew and a new ship, the Going Merry, under their command, the Straw Hat Pirates head to an island said to hold a fabled treasure, only to encounter a strange man stuck in a treasure box named Gaimon that has also been looking for this treasure.

Long Summary
While at sea Usopp daydreams but none of the crew is paying any attention. Since the crew have increased to four, Luffy wants to make a flag/mark. With 50 years of experience in painting walls Usopp creates a flag/mark for The Mugiwara Pirates. He also paints the sails as ordered by Luffy.

Their first destination is Legendary Treasure Island. There they encounter strange looking wild animals. ''Get Out of Here! Get Out of Here! the Guardian God of the island commands.'' The Guardian God attacks the Mugiwara Pirates. When all the attacks fail to hurt Luffy, the Guardian God runs away. Luffy catches him and finds out that he is actually just a man living in a box. Twenty years ago he was a pirate who fell into a box and was stuck ever since. Luffy and Zoro tries in vain to pull him out of the box. Luffy introduce himself as the one who is going to be the Pirate King after getting One Piece. Gaimon (the Guardian God) fills Luffy in on what happen to him 20 years ago, how he fell into the box. Gaimon takes the pirates to the hill where there is treasure, when Nami promises to get it for him. Luffy rockets up the hill and find five treasure boxes but he refuse to hand them over to Gaimon. But Gaimon already knew/felt that the boxes are empty.
