The Carmichaels get a visit from the "Great Aunt T", who came over to celebrate Kwanzaa with the Carmichaels. The holiday, which the Carmichaels normally don't celebrate, celebrates the honor and greatness of the African people. However, Susie feels that she isn't as great as her brothers and sisters, all of them examples of greatness in the Carmichael family. With a little help from the Great Aunt T. and the Rugrats, she learns that everyone is great in their own way, making "Kwonzo" a joyous holiday. We also go back in time, when Aunt T met Dr. Martin Luther King, Jr. in the most unusual place -- at the side of the road with car trouble, as well as the time Aunt T funded Lucy's tuition money for Harvard Medical School.
