Here's all I could dig up on it: "There's a deleted scene where it shows Simba and his friends eating some tourists after they get stranded when their Jeep breaks down. The animators wanted to make the film more realistic but decided to exclude that scene in order to get a G rating." Apparently it's one of those easter eggs you get in DVD's sometimes...
I'll keep digging around, and keep you posted
