Part 2 of 7, of a playthrough of "Barbie Diaries: High School Mystery" for the GameBoy Advance. Barbie finds a locked item in the chemistry room. Kevin gives her a device, which helps her figure out the combination. Inside is another auction item, a cell phone.

SA sends an MP3 next. Kevin helps Barbie decode it. Tia identifies the song as the one that's played during morning announcements, so Barbie goes to the Principal's Office. Principal Peters makes Barbie sort mail. Inside the nearby CD bin, Barbie finds another auction item.

Barbie meets Courtney in the chemistry lab. Courtney got a text which is a scrambled-up word. Barbie solves the puzzle and finds the word is "speaker". She asks Kevin, who thinks the word refers to the speaker podium in the auditorium. To get there, Barbie has to get through the cafeteria. There's a big food fight going on, so it's not easy!
