At the age of ten, Noodle arrived on Murdoc's doorstep in a FedEx crate, in immediate response to the ad they placed for a guitarist in NME. She could not speak any English beyond the word "Noodle", thus earning her the alias. She quickly got settled in England with the Gorillaz, and was accepted as the fourth member of the band. In Rise of the Ogre, it is revealed that during the band's hiatus in November 2003, Noodle went back to Japan to find out the truth about her past after being haunted by strange nightmares while on tour. Upon her return to Japan, Noodle regained her memory after hearing the code-phrase "ocean bacon" at a restaurant. There she coincidentally met with her creator/mentor, Mr. Kyuzo, who was working as the head chef in the restaurant. Kyuzo helped her make sense of her lost memories: Noodle is, in fact, part of a secret government super soldier project, trained specially as a musician. As a result, she is a master of many weapons, languages, and musical instruments, with a speciality in the guitar, both as a musical instrument, and a weapon. Out of the 23 children created for the project, Noodle was the only one to survive; the others were all destroyed by the government when the project was scrapped. It is widely believed that Max DeVeaux the Squid was behind the project's demise. Mr. Kyuzo had smuggled her to safety in England after reading the aforementioned ad placed by the other three Gorillaz members in NME. Noodle regained the ability to speak English, along with her memories, and was the first member of Gorillaz to return to Kong Studios after their failed international tour. She was alone at Kong Studios for nearly six months; during that time she composed the majority of the Demon Days album as a response to the chaotic cultural climate at the time. Her composition of the album crafted a specific message, as opposed to the debut which was composed by Murdoc and 2D, which had a grimier, more spontaneous sound. Despite her quiet nature, she became the most vocal of the band when it came to describing the album.<br />
In March 2006, the Gorillaz video "El Mañana" was released. In the days preceding the release of the video, cardboard boxes were found in the Kong Studios lobby. The boxes soon moved to Noodle's room, and each day, her room was shown to be more and more packed away until the room was entirely barren. At the same time, the Slowboat (AKA Windmill Island) from the "Feel Good Inc." music video appeared outside of Kong Studios on the website's splash page. Shortly before the release of "El Mañana", the windmill was seen flying away. The video is a continuation of the "Feel Good Inc." video, once again depicting Noodle on the Slowboat, although she appears to be much older in the "El Mañana" video than when she is shown in the "Feel Good Inc" video. The video concludes with the helicopters bombing the crashed windmill. Two days after the video's release, cracks appeared on the walls of Noodle's room on the website (which spread to the ground floor lobby) and the clock on her wall labelled "Armageddon" (the only piece of furniture left behind) gained a fourth hand, and fell to the floor. The cracks grew to the point that part of the roof collapsed, exposing the outdoor sky. Near the end of the month, more boxes were found in the Kong Studios lobby, one of which was labelled "DedEx". They disappeared after the lobby was destroyed. In the book Rise of the Ogre, Murdoc reveals that the "El Mañana" video was indeed "staged" and that Noodle is still "alive". It was stated by Murdoc that Noodle had been planning to leave after Demon Days. According to Murdoc, Noodle is in the Maldives "chilling out", though that was the interview before receiving a transmission from Noodle. When the Gorillaz web site still allowed visitors to tour Kong Studios, a radio could be heard in the basement, broadcasting a distress call from Noodle. The message was printed as an epilogue in the Gorillaz book, Rise of the Ogre: <br /><br />
'Murdoc! Russel... Is anybody there?! It's me, Noodle... Is there anybody there! You need to reply... Helllloooo! Come In... It's Noodle ... I've found the missing code... They're coming!... (quieter) The reception here is really terrible ... (Back to normal volume) MURDOC! ... Murdoc, you got to get the combin...! Come in! They know where you... Mur ...You must get out! ... It's coming from BENEATH the building! You have to get out! ... Murdoc, hurry before it's too late. MAYDAY ...MAYDAY ... Murdoc! COME IN GORILLAZ!'<br />
—Transmission from Noodle (In the epilogue of Rise of the Ogre)<br />
According to a interview with Q magazine, Murdoc found that Noodle had fallen foul of another attempt to take his soul, this time a group of spirits who had taken advantage of Russel's spirit-channelling capabilities. Armed with an ancient spellbook, he set off into the underworld, but failed to find her.
On 22 January 2010, Murdoc hijacked the online NME Radio and Yahoo! radio broadcasts to promote the new Gorillaz album, Plastic Beach. The bassist claimed that Noodle was never rescued after the "El Mañana" video, and that his supposed rescue attempt was a drunken delusion. With Russel's whereabouts still unknown, he and 2D have been working on the third album with the help of a Noodle cyborg constructed from Noodle's DNA from the windmill wreckage. However, due to the improbability of anything Murdoc says and the fact that only DNA was gathered, the status of the real Noodle was in question. It has since been confirmed that the real Noodle is alive. Recently, Murdoc has called Noodle his greatest asset. Noodle is confirmed to be alive in an exclusive new Gorillaz video for the single "On Melancholy Hill". In the video, a luxury cruise ship (called the "M. Harriet" wink is being bombarded by torpedoes coming from pirate WWII Corsairs flying overhead. A crew member rushes over to cabin 13 to warn Noodle (who is sitting, wearing an oni mask) that the ship is under attack by pirates and to take her to the lifeboats. Noodle walks over to her briefcase and opens it, revealing a Thompson submachine gun. She then passes the confused crew member and heads out to face the pirates. She kills one of the pirates, but the other drops a bomb on the ship, sinking it. Noodle is seen floating out to sea in a lifeboat which is later picked up by the now-giant Russel. Murdoc has since posted on his Twitter page that he was surprised to see the real Noodle alive and is claiming to be on his way to retrieve her. In one of the visuals for the live show, Noodle is seen playing a melodica to the track "Broken". In the storyboard for the potential video for "Rhinestone Eyes", Noodle is seen to be carried on the top of the giant Russels head as he swims towards Plastic Beach. Once the fighting stops near the end of the storyboard, she is seen to step out of Russels mouth, and removes her cat mask, revealing some scarring to her face and eye.<br />
