The Lion King
Timon found Simba along with Pumbaa when Simba succumbed to heat exhaustion. He decided that they should take him in so they would have a major predator on their side. When Simba wakes up, they teach him their philosophy, "Hakuna Matata". He also introduced Simba to a diet of bugs to stop Simba one day eating himself and Pumbaa. They lived happily with Simba, until his childhood friend Nala arrived. After learning Simba is the king, and that he was going to reclaim his kingdom, Timon was all for helping him. He and Pumbaa used themselves as bait so that Simba would have a clear shot at Scar. At the films end, Timon decides to stay and live with Pumbaa and Simba at Pride Rock.
