Prior to her announcement, she also had a doll made of her by BLYTHE, the doll was designed by galaxxxy. This doll was not for sale and was display only, but used in promotion. Kei based her Vocaloid design on the doll.
Galaco's image first appeared on T-shirts and posters in the Vocaloid Shop, however, the images of her prior to her announcement were either pixalated or appeared as silhouette form.
Due to the fact that she was only obtainable via competition, its was only possible to legally gain access to Galaco by using another pre-bought Vocaloid3 voicebank, although her software itself still acted as a normal standard Vocaloid vocal library. She is also the first case of needing a previous Vocaloid to gain access to a completely new voicebank of a new character.
