作曲：

Standing in between extinction in the cold

And explosive radiating growth

So the warm blood flows

Through the large four chambered heart

Maintaining the very high

Metabolism rate they have

Mammal mammal

Their names are called

They raise a paw

The bat the cat

Dolphin and dog

Koala bear and hog

One of us might lose his hair

But you're reminded

That it once was there

From the embryonic

Whale to the monkey with no tail

So the warm blood flows

With the red blood cells lacking nuclei

Through the large four chambered heart

Maintaining the very high

Metabolism rate they have

Mammal mammal

Their names are called

They raise a paw

The bat the cat

Dolphin and dog

Koala bear and hog

Placental the sister of her brother Marsupial

Their cousin called Monotreme

Dead uncle Allotheria

Mammal mammal

Their names are called

They raise a paw

The bat the cat

Dolphin and dog

Koala bear and hog

The fox the ox

Giraffe and shrew

Echidna caribou
