— Oyster’s catchphrase
When Phoebe first saw him, she had a huge crush on him because of his bad boy image and his beautiful song, "Goodbye Mikayla". Barb laughed at the fact that Phoebe's crush's name is "Oyster!" when Max introduced her to Oyster, as his band-mate. While Phoebe changed to a "bad girl" image to impress Oyster, Max tried his best to break them up because he didn't want his band-mate dating his sister.
When they finally go on a date, Phoebe realizes that Oyster is obsessed with his guitar and in fact, the song, "Goodbye Mikayla", was about his former guitar. Oyster reveals that he only wanted to date Phoebe because his guitar chose her. Phoebe uses telekinesis to make the guitar choose Max's band. Oyster then heeds his guitar's 'decision' and officially becomes a member of Max's band.
After that Oyster hangs out a lot with Max and the other band mates, Gideon and Wolfgang. Oyster and the rest of Max's team tried to become friends with Phoebe's friends in The Neverfriending Story but Max and Phoebe went to great lengths to stop them from becoming friends. Their plan didn't work in the end. Oyster hangs out with Phoebe's friend Cherry in Doppel-Gamers as they play a video game together with Max and Phoebe.
As seen in Doppel-Gamers, Oyster has become curious about Chloe Thunderman because she is way too old for a 6-month-old. In the same episode, he points out the man-shaped holes in the Thunderman's house ceiling. When Phoebe and Max realize that he might find out their secret, Cherry offers to distract him.
When Max quit his own band to hang out with more "shady characters" in Exit Stage Theft, Oyster tries to keep the band together and even knits a new guitar strap for him.
In Date of Emergency, Oyster and Cherry become officially a couple, "Choyster", and go on a triple date with Allison and Max and Phoebe and Gideon. In Ditch Perfect, when Max wants to break up the band, Oyster admits that he wants the band to break up to because he wants to spend more time with Cherry.
After they disbanded the band, most of the band members started a new club called Marine Teens, which is like the Green Teens. In Looperheroes, Principal Bradford confirmed all 3 of the clubs, "Tambourine Teens" as well. Bradford booked all 3 of the clubs to use the cafeteria so that he could watch the chaos that'll happen.
Oyster is a little out there. He has infatuations with his guitars that are near and dear to him. Oyster has a rocker personality.
