Calca and Brina appear as humanoid dolls. Dialogue in Final Fantasy IV implies the dolls in that game were normal toys, while in The After Years they appear the size of small children. Calca wears blue clothing, while Brina wears red clothing, but in some games these colors are their bodies and they wear no clothes. Their clothing in Final Fantasy IV is identical save for the PSP release, when Calca's body is blue while Brina has a red body with a white skirt.
