Moo Deng has become something of a pop culture phenomenon — her fame was even addressed in a recent “Saturday Night Live” Weekend Update segment.

Humor aside, the zoo’s team has expressed concern over how fame has led to bad visitor behavior.

Some fans have thrown things at the hippo to wake her up for the perfect picture, while others have splashed her with water.
