Miss Lina’s ballerinas

In four rows of two, Miss Lina’s eight ballerinas – Christina, Edwina, Sabrina, Justina, Katrina, Bettina, Marina, and Nina – dance to the park, at the zoo, and even while doing their schoolwork. They are one perfect act, but when Miss Lina introduces Regina, a new girl, the group of nine’s steps become a mess.
