There is no such creature as a green platypus.
A cow's bladder can hold approximately 10 to 15 liters of urine, depending on the size of the animal. The bladder is relatively large compared to other mammals, reflecting the cow's substantial body size and hydration needs. Its capacity allows cows to store significant amounts of urine before needing to relieve themselves.
A male platypus is 50-60 cm in length, and weighs from 1700 grams to 2kg.
No, your brain is one of the larger organs. If your bladder was that big you would probably have some sort of disorder.
The platypus's burrow can be anywhere between 10 and 30 metres long (up to 100 feet).

A baby's bladder can only hold around one ounce of fluid at a time. As they grow, their bladder does as well and they can hold more.
The bladder expands when it is increasing in capacity. The more urine deposited in the bladder, the larger it will need to be in order to compensate. If the bladder gets too big, it will result in infection or an ulcer.
Platypuses are fairly constant in their size. A male platypus is larger than a female, being 50-60 cm in length, and weighs around 2kg.
Platypuses a not born: they are hatched from eggs. Although mammals, they are egg-laying mammals, or monotremes. A newly hatched platypus is about the size and weight of a bean. It is blind, hairless and completely helpless.
