Irwin's rookery is a group of penguins.
When Timon and Pumbaa visit Antarctica and realize that there are no ants in the continent, they go to a boat stop where they will be taken to Bermuda. While waiting for the boat, they meet Irwin, who shows them that he has two extra tickets since none of his old friends want to go to Bermuda with him.
When the three get on the boat, they see Irwin's rookery say goodbye to him. Timon notices that all of Irwin's friends are injured and he later realizes that it's due to the penguin being clumsy and accident-prone.
