The Wazoo is an animal park in Perth (Short for Western Australia Zoo), which has become so unpopular due to it's poor treatment of animals, that the park has in many means become synonym with shit and arse, as it is some of the worst profanities known to Australians.

Famous mascots; Peter the paraplegic platypus, Ike the inbred iguana and Casper the rotting kangaroo corpse in front of the entrance.

The zoo is also known for it's inbred hairy dogs, the Shit Zoo dogs (Australian spelling: Shih Tzu)
