Chimpanzees

"This ain't a rescue mission, ape. You're on your own."

- Steve Haines Chimpanzees are animals that appear in Grand Theft Auto V. Although not appearing in the wild, they appear during the mission "Did Somebody Say Yoga?" while Michael is hallucinating. They also appear in the mission "Monkey Business".

Overview
In the mission "Did Somebody Say Yoga?", Michael has a bizarre drug-induced hallucination in which he is in an alleyway surrounded by angry chimpanzees.

These animals appear later on in the storyline, in the mission "Monkey Business" inside the Humane Labs and Research Facility. The apes are all in cages, and appear to be in a severely agitated state, possibly suffering from the effects of animal testing or due to the shootout. During the mission, at some point Haines will kick one of the cages, making a random comment before leaving. They can be shot by Michael.

A chimp actor named Chippy appears in the film Meltdown, acting as the stereotypical animal comic relief of many modern movies.

Three Masturbating Monkeys, a group of self-pleasuring chimps, go on to win Fame or Shame.

They also appear in the movie trailer The Simian; at first one is shown being chased by the military, then many are shown invading a city, using weapons including a Minigun and even driving a Sanchez.

Trivia

 * Although called monkeys in the game, they are technically not monkeys at all, as this term more correctly refers to primates with tails. Instead, they are chimpanzees, a kind of ape.
