Yeah - hippos are bad news and most critters won't mess with them. They look big, fat and floppy. But they are fast, strong, huge, and can be very aggressive and territorial.

Often hippos and crocs will kind of co-exist. The crocs won't bother the hippos too much as they know the danger of it.

I don't know if I can find a clip of it or not - but I saw a nature show where a croc was among a group of hippos. All was well till the croc made a move toward a baby. The croc was quickly stomped into the river bottom - permanently - by the rest of the hippos.

lol good video.
Fact more people are killed by hippos then crocs every year and hippo is no push over .
