The Notebook is a key item in Endless Ocean: Blue World. It is a small, black, leather-bound book that records and compiles many different pieces of information from throughout the game, such as events of the plot, detailed information about locations, and information (as well as clues) relating to quests.
The Notebook records information under seven different categories, titled Story, Quests, Special Requests, Treasure Rumors, Character Profiles, Area Information, and Diving Skills. Each section is useful for different purposes and can be found below.
Story
- See also: Endless Ocean: Blue World
The Story section of the notebook details and summarizes the journey of L&L Diving Service as you progress through the game. It lists six "chapters" of the game, each with a brief summary of events that transpire over the player's journey.
1: The Song of Dragons
There is a legend about the Song of Dragons that originated in the Pacific Rim.Intrigued by the story, you took a leave of absence from college to visit the Pelago Commonwealth in the South Pacific. By chance, you ended up working for L&L Diving Service, run by the former world-renowned marine adventurer Jean-Eric Louvier.
On your first day, you went diving with Oceana, Jean-Eric's granddaughter and the company's only employee. She dropped her pendant during the dive, and it made a strange sound... which inexplicably caused a humpback whale to turn violent. The pendant had belonged to Oceana's deceased father, Matthias.
This prompted Oceana to set off alone to recover another pendant that had been lost at sea around Deep Hole. Jean-Eric entrusted you with the Pulsar, which you used to drive away a shark that had trapped Oceana. You found the lost pendant and discovered that the two fit together to reveal a mysterious verse.
2: Phantoms of the Castle
The mysterious verse engraved on the pendant left by Oceana's father pointed to Valka Castle. These ruins lay on the seafloor in Ciceros Strait in the Aegean Sea, an area where the legend of the Song of Dragons was still passed down.Determined to solve this mystery, you went to Ciceros Strait with the Louviers, where you were challenged by a salvager named GG and hindered by a ferocious man-eating shark known as Thanatos. Following the clues you found, you made your way to Valka Castle.
Many rare items sank with the castle, and one of them, a map of the circular earth, left a strong impression on you and Oceana.
Just as you found the map, a loud noise came from beyond the castle--the Song of Dragons?
You managed to escape the King's Chamber after a trap sealed you in, then discovered a secret room and returned to the surface with an ancient lapis lazuli slate called the Okeanos Tablet.
3: Pole to Pole
You went to an aquarium in Japan looking for a prodigious scientist said to be the only one capable of deciphering the Okeanos Tablet. She turned out to be a gifted young woman named Hayako Sakurai. After you did some work in the Arctic for her, she deciphered the slate:The treasure of Pacifica sleeps behind the bronze door in the abyss. The fissure filled by the circular ocean shows the way to the queen's tomb. Offer your flute to the sun of morning, noon and night and the dragon's song will open the gates to treasure.
Jean-Eric was disturbed by hearing about the Pacifica Treasure that had led Matthias to his death. In the end, Oceana and Hayako convinced him to investigate it. Following reports of sailors hearing the Song of Dragons, you headed for the Antarctic. But just as before, the Song of Dragons was followed by danger, and you barely escaped with your lives. Convinced that the Song of Dragons really did bring bad luck, Jean-Eric refused to pursue the mystery of the song or the treasure any further.
4: The Second Slate
Jean-Eric had become estranged from his son Matthias because he continued to search for a treasure that Jean-Eric didn't believe existed. Jean-Eric was tormented by guilt, but Oceana convinced him that her father wouldn't have wanted him to feel this way.The following day, GG came to Nineball Island and admitted that he was also looking for the Pacifica Treasure. At his request, the group left for South America, believing there was some information about the Song of Dragons and the treasure in the Cortica River.
Together with GG, you went up the dangerous Cortica River and discovered ancient Okeanos ruins that held a second tablet. The contents were astonishing, saying that the Okeanides controlled dragons using a Dragon Flute, which was both a map and a key to the hidden Pacifica Treasure.
The Dragon Flute was made up of three parts... If the pendants Matthias left Oceana were two of those parts, where was the last piece? It seemed that Jean-Eric was hiding something...
5: The Mystery in the Abyss
According to Jean-Eric, he and Matthias found the three parts of the Dragon Flute by chance 15 years ago while exploring the Zahhab Region of the Red Sea. Matthias pushed on to the Zahhab Region Depths in the submarine HD-9 to look for the treasure, but something went wrong. When rescuers arrived, the submarine was empty and only two parts of the flute were found.Matthias's submarine sank in the Zahhab Region Depths... could the third piece of the Dragon Flute be inside?
You defied the dangerous working conditions in the deep to explore the sunken HD-9 and found a waterproof sack containing the last piece of the flute.
The waterproof sack also contained Matthias's last letter to his father. In it, he said that he still loved his father, and these words melted the ice in Jean-Eric's heart.
6: Forever Blue
The three pieces were combined, and the Dragon Flute was finally complete. However, the map it held wasn't a normal one...You realized that it could be projected onto the map of the circular earth to establish the location of the Pacifica Treasure.
Upon following the map to the marked location, you found some colossal submerged ruins. After joining forces with Oceana, Hayako and GG to search the ruins, you found the Pacifica Treasure left behind by the Okeanides deep inside--a gigantic golden statue of a goddess.
As soon as you laid eyes on it, the reverberations of the Dragon Flute caused the ruins to collapse and your group quickly escaped, leaving the treasure to rest once more at the bottom of the ocean.
Quests
Quests are useful missions that the player can embark on as a break from the main storyline or for additional items and loot. They usually take quite a bit of time and effort to complete, with multiple parts to each quest. There are eight quests in total, each of which has its own rewards along the way.
Be the Best Trainer!
- Main article: Be the Best Trainer
The Be the Best Trainer! quest revolves around the player's dolphin partners and a man named Finley, who visits the player after performing a few dolphin shows. This quest is the only method of obtaining nine of eleven dolphin partners in the game, and while not necessary, and while dolphins do not differ in skill or speed, it is a fun sidequest for training dolphins, putting on shows and gaining titles and items.
Fragments of Memory
- Main article: Fragments of Memory
The Fragments of Memory quest follows the story of ML, a diver who suffers an accident and, consequentially, memory loss. The player must take photos of various creatures in order to help him regain his memory, with one of the final photos being of Oceana.
Find the Blue Bird!
- Main article: Find the Blue Bird
The Find the Blue Bird! quest revolves around a titular blue bird who the player finds on the pier of Nineball Island. The bird will speak to the player and fly away towards an island Gatama Atoll, beginning a long goose chase as the player chases the bird to various locations across the world, finding a new item or piece of equipment at each of its landing spots. The quest ends with the bird returning to the player's pier, where it can be occasionally seen afterward. This quest is a good way to gain many items and much gear.
Pride of the Salvage King

Voice of the Night Sky
- Main article: Voice of the Night Sky

Save the Aquarium
- Main article: Save the Aquarium
The Save the Aquarium quest centers largely around Hayako and the Aquarium, as the player aides her and Mr. Kaimoto in boosting the success and popularity of the aquarium so that it does not lose funding.
