Bowser Jr makes a KoopaTube (parody of YouTube) channel to mock his siblings.
KoopaTube contains examples of:
- Diss Track: When the Koopalings had enough of Bowser Jr roasting them they decide to give him a taste of his own medicine with a diss track.
- Laser-Guided Karma: After always getting the Koopalings in trouble for everything, Bowser Jr loses all of his subscribers and breaks his laptop ruining his chance of continuing his channel.
