The Goblin's Ponygirl Series by Vanessa Cardui

Jisi is a goblin. She's only about twice as big as a an inconvenient size for someone who likes to fistfight raccoons. But what she lacks in height she makes up for in self-confidence, a penchant for exuberant chaos, and a diploma from a magical correspondence course (which she absolutely did not cheat on).
