Babar is welcomed back to the Great Forest, where he reunites with his old friend Cornelius and the rest of the elephants. Meanwhile, Lord Rataxes, the leader of the rhinoceroses, mobilizes his forces in preparation for war against the elephants. Babar devises a plan to stop the war: he paints monster faces on the backsides of elephants and has them walk backwards in their approach towards the enemy. The plan succeeds in forcing the rhinoceros troops to retreat in fear, and Babar then has Arthur apologize to the abandoned Rataxes for offending the rhinoceroses, thus restoring peace to the jungle. For his brilliant idea and bravery, Babar is asked to be the new King of the Elephants; he agrees on the condition that Celeste be his Queen, which she accepts.
