Name: Lost at Sea
Released: 2007-08-27

Hiroki takes Yumi's diary, but Ulrich discovers it. At the same time, Jeremy devises a program aimed at rescuing William from X.A.N.A.'s grip by locating him in the Digital Sea. However, when he uploads the program to the Skid, the sonar malfunctions, prompting the team to head back to Lyoko. During their return, they encounter the Kongers, leaving Yumi stranded in the Digital Sea. X.A.N.A. tries to exploit her situation, but this alerts Jeremy, who guides the others to her. After battling the Kongers and William, who pilots his own ship, the Rorkal, they make it back to Earth. Ulrich discreetly returns the diary to help Hiroki make amends with Yumi.
