Dr. Eggman and his two badniks Scratch and Grounder were all far ahead within the Death Egg, while the other racers were getting closer and closer. As the racers followed Eggman through a strange warp, they all felt gravity going through them as they warped to light speed, leaving the Death Egg far behind as they journey far up into outer space and somehow make it onto Rainbow Road.

"Ohohohoho! Let's see these chumps handle this!" Eggman chuckled as he fired some Smart Bombs from his Egg Carrier, watching with glee as the racers got caught in gigantic, fiery explosions while he steered towards the right, heading downward the rainbow-colored road and steering towards the left.

As the racers tried to start up again, Yoshi and Dr. Hoshi, followed by Godzilla, Mario/Luigi, Pikachu, and Baby Mario/Baby Luigi (who were revived for the race specifically by Master Hand back on Earth), all managed to zoom out and headed down the road, turning to the right and then going around the wide left bend. Dr. Hoshi grabbed a triple pack of mushrooms from one of the rainbow-colored item boxes, and he tossed one into the engine of the Turbo Yoshi, the vehicle zooming faster. Godzilla, however, simply took a chance and jumped off the course, landing firmly down on the mystical rainbow-colored road again below as he turned around and followed Eggman, firing his atomic breath at the bottom of the Egg Carrier. Eggman, Scratch, and Grounder all screamed as they hung tightly, but Eggman managed to make the Egg Carrier hover above Godzilla, and as they allowed the gigantic, green-colored reptilian King of the Monsters pass, Scratch and Grounder got out their bazookas and fired several missiles at Godzilla. This did not affect him, but it did annoy him as he watched Eggman steer ahead, with Scratch still firing missiles at his upper chest while Grounder released traps on the road below.

Baby Mario steered his trusty red wagon with ease, while Baby Luigi was using the fan he has acquired from an item box to knock the traps off the road. As they turned to the right and headed towards a large boosting zone, it was then that out of nowhere, ROB the Robotic Operating Buddy appeared besides Baby Mario and Baby Luigi, greeting the two babies as the other racers took the opportunity to zoom ahead.

"ROB!? What are you doing here!?" Baby Mario and Baby Luigi exclaimed in unison as Baby Mario swerved to the right to avoid Pikachu's Thunder Jolt attack to electrocute the motion sensor bomb ahead.

ROB looked at the clear, dark space above him, and then down at Baby Mario as the wagon zipped with fast acceleration on the boosting gap. "I couldn't leave you two alone, so I decided to come all the way into outer space to aid you two."

Baby Luigi's eyes were filled with tears of joy as he hugged ROB tightly. Baby Mario rolled his eyes, but he screamed as he was nearly pushed off the rainbow-colored road by Boggy the Polar Bear, who was sliding his way through, followed closely by Kirby. Baby Mario swerved towards the left, and got back into the middle of the road. However, this didn't mean easy riding, as several of Eggman's robots appeared along the asides and started firing at the racers. One laser popped one of the wagon's wheels, and both of the baby Mario Brothers held onto each other and screamed as they went spinning around. ROB, however, was quite content, and he grabbed a Gyromite disk out of nowhere and placed it in the place of the popped tire, stopping the wagon from spinning and steering the wagon while Baby Mario and Baby Luigi were both in awe.

As the racers went along the spiral, a gigantic, purple-and-yellow colored, quadruple robot appeared and started to shake the entire road. Yoshi managed to switch positions with Dr. Hoshi and he tossed several of his homing, green-spotted eggs at the robot, distracting it as other racers followed behind the reptilian pair, with mario tossing several of his red fireballs at the robot and Pikachu adding in his Thunderbolt attack, which luckily paralyzed the gigantic mechanical beast. Boggy, however, was not lucky enough, as he was caught by the quadruple robot and tossed off the road, going into space as he was suddenly sucked into a mysterious, blue warp portal.

As the racers stopped steering on the spiral, they went upwards the rainbow-colored road. Beyond them were several sparkling, golden stars that formed on the path, whilst the traps that Grounder has set often make them difficult to get. As Alec Trevelyan ran as fast as he could, he tripped over the ledge of the spiral, and he tumbled down into space, screaming as he was sucked into a blue-colored warp portal. The other racers became cautious and they stayed close to the middle as possible, while swerving left or right or jumping over the traps within the middle.

Timber the Tiger and T.T. the Analog Clock were both sticking close to each other, both of them swerving to the left and then to the right as they followed the others on the curvy road. Jumping over a motion sensor bomb which exploded as Timber accidentally slipped over leftover oil, T.T. glanced behind him and watched as Timber fell off the course and got sucked into a blue warp portal. Gulping, T.T. turned around, only to crash into several red-colored robots, which all malfunctioned in unison and caused a big explosion that not only destroyed T.T.'s car, but sent T.T. going into space as well, being sucked in by the blue warp portal. The remaining racers became more cautious as they all went upwards in the tunnel ahead, being above the rainbow-colored road as they zip on the zippers and use the boost of velocity to catch up to Eggman and his two badniks, who start coming up with their own cunning ways of getting rid of the racers...
