This is a spin-off of the cartoon "Dude, That's My Ghost!", It follows the plot of the episode Spencer replaced his father in charge of a group of cheerleaders in a presentation. This plot involves Spencer starting to train the group for various competitions, and since the episode Billy Joe purposely helped the opposing team to ensure that Spencer would enlist his help, and the help ended up working, so Spencer guaranteed that they would all have an object that was Billy's, for them to hear and see him because he is going to participate in the team's presentations. And a storyline of a boy and a lot of girls always ends up having a joke. Spencer accidentally entering the dressing room while they are changing, there could be a scene where they say that Billy cannot enter the dressing room, and then Billy Joe becomes a cheerleader and asks if he can now, and they answer that do not.
There could be an episode or more than one where Billy Joe wants to do the music of the performance using Spencer to play it live without anyone being surprised (with Spencer pretending to be playing the guitar when it is actually him).
