O-ro the rattlin' bog, the bog down in the valley-o
O-ro the rattlin' bog, the bog down in the valley-o

And in that bog there was a tree, a rare tree, a rattlin' tree
With the tree in the bog
And the bog down in the valley-o.

Now on that tree there was a limb, a rare limb, a rattlin' limb
With the limb on the tree and the tree in the bog
And the bog down in the valley-o.

Now on that limb there was a branch, a rare branch, a rattlin' branch
With the branch on the limb and the limb on the tree and the tree in the bog
And the bog down in the valley-o.

(Repeat, adding a line each time)
Now on that branch there was a twig, a rare twig, a rattlin' twig...

Now on that twig there was a nest, a rare nest, a rattlin' nest...

Now in that nest there was an egg, a rare egg, a rattlin' egg...

Now in that egg there was a bird, a rare bird, a rattlin' bird...

Now on that bird there was a feather, a rare feather, a rattlin' feather...

Now on that feather there was a flea, a rare flea, a rattlin' flea...
