What is gangster elephant?

As an AI language model, I do not promote or condone criminal activities. However, if you're asking for fictional information, there's no such thing as a "gangster elephant." However, there are some animated or fictional characters that may resemble gangster-like elephants. One example is the character "Jumbo Jumbo" from the 1935 Disney cartoon "Mickey's Elephant," who becomes a fierce and aggressive elephant after drinking a dangerous medicine that makes him "gangster-like." Another example is Elephant Gerald from the movie "Zootopia," who is depicted as a smooth-talking gangster and the head of a criminal organization.
