 Bowser Jr. is a boss that appears in Finish! Bowser Keep. It is the 52nd boss fought in the game.


Bowser Jr. first appeared in Super Mario Sunshine as a main antagonist to Mario. In this battle, the Baby Bowser sprite from Super Mario World 2: Yoshi's Island is used, as there is no 16-bit sprite for Bowser Jr. The giant moon also originates from the same game, but appears in the area where you fight Raphael the Raven. The shockwaves that appear when Bowser Jr. ground pounds the floor are from Super Mario World.

In Battle[]

After you beat the Moon, you will jump on the moon where you will fight Bowser Jr. He rapidly runs around the moon, sometimes doing a ground pound on the floor, spawning three shock waves that circle around the moon. You have to jump on his head four times to beat the boss. After the third time, he will start becoming faster and harder. Hit him one more and the boss is down.


  • The fight with Bowser Jr. is actually similar to the fight with Raphael the Raven in Super Mario World 2: Yoshi's Island. Because in both fights you fight on a moon, and both bosses spawn shock waves when the boss hits the floor.
