This is just a guess...But hippos go under water....Steve

Is the hippo facing a river, stream, or a dry wash? And does it look something like this! td

Closest thing would be rain runoff. I believe it's likely "close" to what I'm looking for and is "looking" almost directly where the signs seem to be indicating.
