Now tell us about the Patypus!
OK, I will tell you about the platypus (or Patypus as you call it)

:
Biology, including herpetology and mammalogy (both of which I studied in college), ornithology, ichthyology, entomology, marine biology, and botany (which I am studying now, on my own) is my field, along with behavioral psychology and some other things which aren’t relevant here.
IMHO the duck-billed platypus is one of the most fascinating animals on the earth.
First, let’s examine the biology of the platypus:
“Pride of place goes to the platypus,
a creature with very amazing features which are only seen in very diverse species: mammals - mammary glands (all), three ear bones (all), beaver like tail, fur (many); reptiles - cloaca (all) (however, it does have a uterus and as in birds, only one of the ovaries is functional), egg laying (all), poison (snakes) spurs for defense; birds - duck like bill (which is soft however), it breathes through the bill like the duck, duck like webbed feet (however, these feet have claws in the front and spurs in the back); fish - it has an amazing electro receptor (paddle fish) in its bill which allows it to catch prey under water while its eyes are closed and its hearing shut, it also has a very large vocalization range more bird-like than anything found in other mammals (except man). The platypus is perfectly designed for feeding and swimming in the water and it has to be - it eats about half its weight in food a day! However, it lives on land in burrows it digs with its claws and can also feed on insects and other land creatures.”
This article also offers an aboriginal tale of how the platypus came into existence:
The platypus resulted from a young female duck’s disobedience. Duck lived with others of their kind in a sheltered river pond. All of them were in constant fear of Mulloka, the Water Devil, and never strayed far from their pond. But one day, against the advice of her elders, Duck ventured downstream and eventually found herself at a patch of grass on the riverbank. Unaware that this was the territory of the lonely Water-rat, she climbed out. Hearing duck, Water-rat emerged, threatened her with his spear and, dragging her underground, forced her to mate with him. By the time of egg-hatching, Duck was ashamed to have to lead out two extraordinary offspring. They had bills and webbed feet, but instead of two feet they had four and instead of feathers they had fur, while on each hind leg they had a sharp spike like Water-rat’s spear. The first members of the platypus race were born.

CREATIONISM
Is the duck-billed platypus a joke God put on earth to confound and confuse us? Is He up in heaven laughing at us (though always with love) as we struggle to understand such a strange creature?
What about creationism? Although I don’t consider creationism to be a science, this thread is not restricted to science alone and creationists should certainly have their say:
"Monotremes possess at least two similarities to Marsupials that suggest a possible link related to their origins. First and most importantly they are both mammals that have an alternative reproductive system to the majority on earth. Neither have a placenta, and both give birth much earlier than placental mammals. The young of the marsupial matures following birth inside a pouch. The second difference suggesting an associated origin, is the fact they are also the only other natural mammalian inhabitants of Australia. Prior to the modern introduction of placentals such as the dingo, the continent was inhabited exclusively by monotreme and marsupial mammals. Most of the 140 species of marsupials in Australia are found nowhere else in the world, and the naturally occurring marsupial in the United States is the possum, Didelphis marsupialis. This distribution pattern must be explained through natural affects upon these animals following their release from the ark.
[The following quote does not follow immediately and the site should be accessed for further study of a creationism theory.]
"This creation science theory may finally lay to rest a mystery that has caused a great many people to believe in the evolution of all animals from a common ancestor.
The absence of plancentals or exclusive existence of multiple marsupials and the monotremes on Australia can not be explained by a natural postflood migration from Mt. Ararat in Turkey. This very fact has even caused a great many Christians to instead accept that these inhabitants must have evolved in Australia from a single ancestor.

The following link does a good job of debunking some creationist views of the present form of the platypus. I would like to provide the article as a whole, but in keeping with CAF rules, I will provide a link for anyone who is interested. I recommend that this article be read from beginning to end, as it provides both the creationist view and the reasons why the authors of this article believe that creationism does not explain the platypus or its putative journey from the Ark.
