Nella the Princess Knight Nella isn't your average princess, but she is a princess-knight -- a hero unlike any who have come before her. Working with loyal knight Sir Garrett, his trusty steed Clod and glamorous unicorn Trinket, Nella breaks barriers, challenges expectations and fights for justice every time the group heads out on an adventure. No matter how tough of a challenge she faces, 8-year-old Nella always stays true to herself through her determination, power and courage. The preschool series features a social-emotional curriculum intended to foster relationship development and empower preschoolers to be courageous.
