Castiel was sitting in Heaven at Humanities beginnings, settlements that soon will become towns, cities. Then, coming from God's sun, flew into his arms a white filly, with horns, wings, with a pink mane and tail. He brought her to God, and he said: "Raise her."

Crowley just fell into Hell, died after his time was up. Starting out as a tortured soul was the easy part, now that he's a demon, the high ups decide to make things harder for him. He must raise a demonic pony.

John Winchester left his boys in the care of fellow Hunter Bobby while on a hunt. It was 1991, early spring, and Sam ran off to explore the woods. Not far from Bobby's backyard, Sam finds a small, blue creature. Experience taught him to usually shoot the strange first, but rather than pulling his gun, he picks it up, realizing it's crying, scared. While his brother, Bobby, and his dad especially were on edge of it, they all soon learned to accept the creature. Not long later, she joins them in the "Family business."
