When Fitna influences the animals against this through propaganda, the King decides on a form of 'democracy', thinking that no one will be able to stand up to Shahzada.

He and Shahzada compete for the crown through many hilarious ways, like press talks and rap battles, while Fitna supports Mangu through influencing the news and reverse psychology.

Eventually, Mangu makes an inspirational speech from the bottom of his heart that wins over the animals.

The Cats are exiled and Mangu starts to live a life of luxury in the palace and neglects his duties as the leader of the jungle.
