ANIMAL | 8:00 pm

Robert Irwin extends the legacy of his late, great father — beloved "Crocodile Hunter" Steve Irwin — as he faces off with Bosco, the most aggressive crocodile in residence at the Australia Zoo, in the new episode "Robert and Big Bad Bosco." Meanwhile, on a much more warm and cuddly note, Robert's sister, Bindi, lends a hand when a koala needs eye surgery.
