Marcus, a former child singer, joins the boat and tries to have a normal life. Cody and Bailey compete against each other in games.
Tropes:
- Celebrity Is Overrated: Marcus tells Zack that while the money and attention from girls he had during his career was fun, being a musician was also a lot of hard work and caused him to miss out on the fun of a regular childhood.
- Former Child Star: Marcus turns out to be Lil' Little, a preteen rap star. However, he was dumped by his record label once he hit puberty, which is why he joined the school.
- I Just Want to Be Normal: The reason Marcus didn't tell everyone who he really was is that he's still bitter over how his career ended and wanted a fresh start where everyone treated him as a normal person.
