Bowser Jr. unleashes a Sonic Roar, stunning anyone caught in the blast. He will then leap out of his Clown Car and paint a box around the trapped enemies with his paintbrush. Opponents not trapped in the box can still take damage from the edges of the box and Bowser Jr. while he is painting. Once the box is done, Bowser Jr. will fill in the space inside with paint, further damaging the ones trapped inside. Bowser Jr. will then hop back into his Clown Car and throw a Bob-omb at the box, blowing up it and the opponents inside with a massive explosion.
