If you want to be as graceful as a swan, you have to train like a horse.
It isnít so easy to be a world-class dancer! Thatís why the elegant Ballerina trains hard every day. Itís not just about wearing a frilly tutu and lacing up her stylish slippers. Sheís got to practice every move and position until she gets them just right Ė otherwise, she wonít be able to do justice to classic ballets like The Brick Separator and Swan Blue Base Plate.
But itís all worth it when the music swells and her performance begins. As she leaps and twirls about on the stage, as the audience goes silent and barely dares to breathe while watching her dance, thatís when she knows that all of her practice has paid off. And itís a good thing too, because you wouldnít believe how hard it is to learn to balance on your tip-toes when you have minifigure feet!
