Sonic and Mario were having a fair race in Seaside Hill, both using vehicles, with Sonic in his blue car and Mario in his unmodified B Dasher. The course was Whale Lagoon, and the two were determined to beat each other.
"May the best humanoid mammal win," Sonic remarked to Mario, chuckling.
Mario nodded back to Sonic in response, giving a thumbs up as the two mascots sped off, with plenty of various Nintendo and SEGA characters cheering.
Sonic went with the northern path, while Mario took the southern path. The two looped past each other as they ended up back on the sand, turning on the left bend on the wooden bridge. Mario rammed into Sonic, with Sonic pushing Mario off as they got onto the grassy path, heading towards the orange checkerboard loops. Mario felt a bit dizzy as Sonic took advantage, zooming right past Mario and going around the right bend on the wooden bridge, resurfacing on the grass path. Mario tried to catch up, but his B Dasher lost some acceleration, which cost him the race as Sonic zoomed on the red and white concrete road, passing the finish line and winning. Despite losing, Mario took it well, getting out of his B Dasher and shaking hands with Sonic, who nodded back as he patted Mario on the back for a good race.
"Races like these are not about winning, kids." Sonic stated as he wagged his left index finger, winking. "It's about having fun."
