Freaky Freshmen
In Chapter 1: Freshmen Day, he is mentioned by the teachers in the Gym going into Group 9.

In Chapter 5: The Lunch Bunch, he is first seen walking up to a table with Alex and Willie to meet up with Jeffrey, Hunter, Heather, Daniel, Cody, Eric, and Douglas for Lunch. He listens to the story of how Jeffrey and Hunter met and he mentions how he remembers that day. He is later introduced to Olivia and Jack.

In Chapter 8: Band Practice, he is seen in the band room with Daniel, Willie, and Douglas when Dakota walks in on them and asks them who they are. After they talk and get to know each other, they start messing around with the instruments until Mick walks in. They then get to know him as well and what almost turns out to be a conflict between Willie and Dakota ends when Garrett tells Willie that Dakota doesn't look like a person he should be messing with. He later tells Mick he can play piano and he and the others start playing their instruments near the end of the chapter.

In Chapter 12: My First Song, he is seen with the rest of the Strawberry Lumps band members when Mick mentions it's time to write their first song. Heather takes on the challenge after Garrett and Dakota tell him they never wrote a song before. Garrett is later seen playing his instrument with the band to the song that has been successfully written by Heather before the chapter ends.

In Chapter 20: Sing It!, he is seen with Heather and Mick at school coming up with song ideas for the band when he suggests that they do parodies of some songs from artists Heather mentioned. Not long after this, Heather takes his advice and she tells the two she'll let them know what she comes up with. After this, Garrett isn't seen for the rest of the chapter.
