| Glass of milk | |
| 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 |
