Lite Brix Girls are a group of young, smart, and creative girls who will run the world someday soon. For now, Ava with her spontaneous personality, has created a LiteUp Girls World in Sunset Island where all her friends; Harper, Kaylee, Madison, Briella & Sophia are allowed to come, share, and explore. The girls always meet Ava and her BFF Madison at the LiteUp Mansion where they hang out and have lots of fun. The light up house is spacious with 5 play areas including living room, bedroom, kitchen, dressing room and in ground pool, so there is plenty of space for Ava to throw a sleep over or party!
