Very unexpected. I am wondering if that croc was injured before hand. Or if it was a female who was pregnant (sometimes they get into a trance like state where they don't have much energy or agility, allowing people like steve corwin to get really close and play with them).
From what I gathered from the dialogue, and from where I found it the croc came out of the water to try and steal the tigers kill... I'm shocked the tiger didn't run...
