Made up a concept for Soarin's parents! Here we have Kolache and Nightshade Zoom, owners of a bakery in Manehattan as well as a coffee shop in Cloudsdale.
When Kolache and Nightshade Zoom met, Kolache was a traveling pastry vendor who moved to every corner of Equestria to earn the bits to start his own bakery, and Nightshade had already gotten her own coffee shop up and running in Cloudsdale. Kolache had been given the opportunity by a kind unicorn to walk among the pegasi in Cloudsdale to share his pastries with them. Up there, Nightshade was none too happy about this earth pony selling pastries in front of her shop, and confronts him to take his business elsewhere. A brief argument ensues, but the two eventually reach an understanding and the two enjoy a few baked treats on the patio of Nightshade's shop after it closes.
Kolache ends up staying until the cloud walking spell wears off, and Nightshade brings him safely to the ground directly below Cloudsdale, and from then on Kolache changed his route to follow Cloudsdale as the city travels across the kingdom. Nightshade visits him below the cloud city every meal break as well as every night after closing.
Eventually Nightshade becomes pregnant, and the two decide to get married at the nearest city they could find, Manehattan. In a rush to find a stable living situation before the foal is born, Nightshade and Kolache combine their life savings to open a bakery in Manehattan to raise the foal, while Nightshade would occasionally journey to her coffee shop in Cloudsdale that she left in the hooves of hired help. A few months later, much to Nightshade's delight, she gives birth to a little pegasus colt, who they name Soarin'!
Around the time their little Soarin' was old enough to go to flight school, Nightshade takes him to temporarily live in the apartments above her coffee shop so he can train under the best coaches, under the lingering fear his flying would not be as strong as other pegasus children. Soarin' eventually starts facing adversity as his peers (and even a few of his flying instructors) had begun to mock his dreams of being a Wonderbolt, saying he'll never make it due to being half earth pony. The young colt felt so small and insignificant that at some point he wanted to quit altogether and just run the bakery in Manehattan with his father. His father eventually talks him down, telling him that he never gave up following Nightshade across Equestria because he believed in their love lasting, and Soarin should do the same for his dreams of being a Wonderbolt because he believes that Soarin will be one of the best if he tries.
As second-in-command to the Wonderbolts in present day, Kolache and Nightshade Zoom couldn't be prouder of their little colt.
