Bowser laughed as he passed Donkey Kong on the DS Bowser's Castle, with R.O.B. in the lead as only four racers were on the track. Waluigi was in the back, with Waluigi chucking a Blue Shell as it zipped around the course, blasting R.O.B. and causing him to fall into the red magma below.

"I'm going to overtake you, Bowser!" Donkey Kong exclaimed as he chucked a green shell at Bowser.

"Argh! Damn you, stubborn ape!" Bowser growled, trying to get back his lost speed as he quickly used a Mushroom he held within his Koopa Klown Kar based kart, speeding up and pushing Donkey Kong into the lava as Bowser laughed heartily.

Kamek was watching the race from high in the sky on his broomstick, shaking his head as he watched R.O.B. win the race, with Bowser staying on the upper path as Donkey Kong and Waluigi fought for third place.

"Oh... I wonder why I keep bothering to try and join these stupid races," Kamek complained as he sighed, flying to one of the other Bowser Castles populating the Koopa Kingdom.
