Rafiki's Stick serves as a walking stick for Rafiki, as well as a weapon though more often he uses it to smack someone over the head. It is an old, long wooden stick with several African fruits tied to it and is intended to aid the old monkey with spiritual matters, but also functions as a useful weapon.
In The Lion King, Rafiki strikes Simba with his stick telling that the past can hurt. When Simba dodges the strike Rafiki asks him what he is going to do. He responses by throwing the stick away before returning back home much to Rafiki's delight. During the battle at the Pride Rock after Scar reveals to Simba and the Pride that he is the one who really killed Mufasa, Rafiki notices a hyena attacking Simba, bashes the hyena in the head hard with his stick to knock it out before confronting and defeating several more hyenas with an impressive selection of martial arts.
In the Timon & Pumbaa TV series, in an episode called "Rafiki's Apprentice," Rafiki's walking stick is portrayed as a magical staff with which Rafiki's nephew Nefu (Neh-foo) messes with to accomplish a chore his uncle tasked him with, until things spiral out of control and Rafiki steps in to right Nefu's wrong. In this episode, Rafiki is also revealed to own many more similar sticks as back-ups and gives the original one to Nefu once he's learned his lesson.
Rafiki's stick in the musical is made out of carbon fiber. Instead of having 3-4 gourds, it has been simplified to one gourd. The stick is much bigger than its holder/user.
Rafiki's walking stick is shown enchanting objects (like a branch to work like a fan or trees to move of their own accord), controlling the forces of nature, calling down lightning, and dispelling magical forces. In the Lion Guard, the staff is used to bring the painting on the Lion Guard Lair walls to life. These paintings show past events that occurred an the staff must touch the paintings in the right order and long enough, for a full story to be seen.
