I have no idea hahaha, I thought it was an animal awesome. I like to watching the life of them 
In my city has a crocodile farm where the Guinness Book record. It is the largest crocodile farm in the world, (i'm not sure when they record)
When I went to the crocodile farm, I always scared because it was a wooden bridge. And crocodile was lying under a bridge. I feel scared if the bridge is broken and the i'm gonna die because they going to eaten me.
So when I went to there i always use my two hands catch rail bridge at all times. You can try to Imagine it's so funny and that people who walk behind me, they always laughing.
