Mufasa shows Simba the Pride Lands and explains to him the responsibilities of kingship and the "circle of life", which connects all living things. Mufasa's younger brother, Scar, covets the throne and plots to get rid of Mufasa and Simba so that he may become king. He tricks Simba and his best friend Nala into exploring a forbidden elephants' graveyard, where the ruthless Shenzi attacks them with her fellow hyenas. Mufasa hears about the incident from his majordomo, the hornbill Zazu, and rescues the cubs. Though upset with Simba, Mufasa forgives him and explains that the great kings of the past watch over them from the night sky, from which he will one day watch over Simba. Meanwhile, Scar visits the hyenas and convinces them to help him overthrow Mufasa in exchange for hunting rights in the Pride Lands.
