When the zebras and gazelles outgrow their grazing grounds, Kion turns to his father, Simba, hoping that he will have a solution. The King points out the Mbali Fields to his son and tells them that Mbali Fields is where the zebras and gazelles can find their grass.
Bunga races back to the small patch of grass, announcing to the herds that the Lion Guard will be taking them across the Pride Lands to a new grazing ground, Mbali Fields. After a minor confrontation with Muhimu, Kion leads a migration to the Mbali Fields, after asking Ono to scout out a route for them.
However, upon seeing the new grazing grounds at the top of Rocky Ridge, Muhimu becomes over excited and starts a stampede through a canyon, which ultimately results in their path becoming blocked. Ono is able to locate another path to Mbali Fields, though caution is required since it involves trespassing into the Outlands. Along the way, Muhimu enters labor, causing Fuli, Ono and Beshte to continue with the bulk of the herds while Bunga, Kion, Swala and some zebras wait with Muhimu.
Later, they finally arrive at Mbali Fields, with a new addition, Hamu, joining the herds.
