Below is a video of a hippopotamus saving a wildebeest (gnu) from a crocodile and then doing what it can to help the wildebeest get ashore:
The hippo's were courteous to the wildebeest and very helpful. The hippos graze at night and the widerbeest during the day so they are familiar to eachother.
Yes and thank you for the Discussion John. Trying to get all caught up here.
