  "description": "Bowser Jr., Bowser's eighth child. He is seemingly the youngest of Bowser's eight children and the Koopa King's favorite offspring (at least, for the time being). His other seven children, who used to help Bowser's plots, have now grown up and sometimes conquered whole kingdoms themselves. Bowser Jr., on the other hand, is allowed to accompany his father in various schemes, such as Super Mario Sunshine and New Super Mario Bros."
