[Verse 1]
Glass of milk
Standing in between extinction in the cold
And explosive radiating growth

[Pre-Chorus]
So the warm blood flows
Through the large four-chambered heart
Maintaining the very high metabolism rate they have

[Chorus]
Mammal, mammal
Their names are called, they raise a paw
The bat, the cat
Dolphin and dog, koala bear and hog

[Verse 2]
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

[Pre-Chorus]
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
[Chorus]
Mammal, mammal
Their names are called, they raise a paw
The bat, the cat
Dolphin and dog, koala bear and hog

[Verse 3]
Placental the sister
Of her brother Marsupial
Their cousin called Monotreme
Dead uncle Allotheria

[Chorus]
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
