The Ukumbusho is a performance that celebrates the friendship between the elephants and the lions of the Pride Lands, as set by Askari, the first Lion Guard and the elephants many Dry Seasons again. It naturally celebrates peace with the lions with the Lion Guard. The elephants get the sunbursts painted on their foreheads using "Peace Paint" to represent the Circle of Life. They're a big part of the tradition. The centerpiece of the entire Ukumbusho performance is the speech between the bravest lion and elephant. During the performance, the lions are offered a branch as a symbol of peace. The performance is held at moon rise.
Ma Tembo instructs her herd to get ready for the Ukumbusho. After Makini arrives, she directs her to some peace paint, while the Lion Guard get ready, with Timon and Pumbaa's help. When Ma Tembo remembers that the Lion Guard is traditionally made up of lions, Makini offers to paint the Guard, but in doing so, she lacks enough paint to finish painting Zito and several other elephants. She is given some time to come up with new paints and she does so, picking some yellow flowers.
When King Simba arrives, the show begins, with the Lion Guard singing "May There Be Peace". But just after Kion greets Ma Tembo as Askari, a swarm of bees frightens the elephants away. After dealing with the bees, the elephants return, where Ma Tembo apologizes to King Simba for the outburst. Although Makini offers to repaint them, Kion suggests trying the show without the paint. When Ma Tembo is hesitant to break with tradition, Simba suggests seeing it as starting a new tradition. Ma Tembo agrees, and the new Ukumbusho begins.
'Ukumbusho' is Swahili for 'remembrance' or 'memorial'.
Ironically, the Lion Guard's attire is a reference to Kid Simba's coat and a mane made out of red leaves during the song: "I just can't wait to be King"
