Lyrics:

In the reptile room
Where the baby screams
Weirder creatures loom
Than in all of your dreams

In the reptile room
Hither and thither
Creatures from Khartoum
Slither any-whither

In the reptile room
Anacondas dance
Will they be our doom?
Will we be their bon-bons?

And you wanna know, wanna know, wanna know why I frown?
Well, I'm smiling, I'm just smiling upside-down

In the reptile room
There's an evil man
In a strange costume
Do not ride in his van

In the reptile room
Are pythons at play
In the murky gloom
What a horrible day
