Pumbaa is a bombastic warthog in The Lion King. He and his best friend Timon live a laid-back life. When Simba runs away from home, he finds Timon and Pumbaa and they sing "Hakuna Matata." Nala comes and Timon realizes that Simba is falling in love with her. Pumbaa and Timon sing in the end of "Can You Feel the Love Tonight" lamenting the fact that they are losing their friend. Simba runs away to confront Scar and Timon, Pumbaa, and Nala return to Pride Rock. Timon and Pumbaa distract hyenas, while Simba sneaks by and defeats his uncle.
Before Timon and Pumbaa find the jungle, Pumbaa says that he is alone in the world. It is possible that he inadvertently lost contact with his family. Also, during the flashback Timon and Pumbaa reveal that Pumbaa had problems with gas when he was younger. They mention that Pumbaa once went to a water hole in the savanna but he let out very smelly gas, causing monkeysto fall from the trees to the ground because of the stink. When Pumbaa came to drink the water, his gas caused all the nearby animals to flee. For Pumbaa, it was very embarrassing.
