History: Sunny Delight was an average pony who lived in Manehattan, but was more of a country pony than a city pony. Her family moved to Ponyville because there was too much crime in the big city. Sunny was very happy about the move. She tried to get to know the Ponyville ponies and make friends, and she's still working on that!
Her cutie mark, a sun, is not a raging sun, it's just... a sun. She was cheering up a pony in Manehattan when she got it, and the pony pointed out she got her cutie mark. It's as simple as that- it's not really much of a story, Sunny knows, but that's how it happened. Her cutie mark represents cheerfulness and her affinity for cheering ponies up.
Example RP segment: It was pouring rain, and Sunny Delight saw a little pony hiding in a box. The foal was very sad and crying, which Sunny didn't like. Sunny went over to the box of the sobbing foal, and offered to give the foal a hug. When the foal took the offer, Sunny asked where the foal lived, and offered to walk him home.
As the two got to the little foal's house, they saw his mother. Sunny walked over and said "I found your son in the rain, and offered to walk him home!" She gave a smile, and then walked home herself.
