Is this it?

"The Crocodile Song" by Roger Green
First verse
Come gather around me children to tell the truth I'm bound
Here's a story when I went to sea and the wonders that I found
Ship wrecked was I one lonely day and cast upon the shore
Now I decided to wonder way the country to explore, explore the country to explore
So I sang, toddle oddle oddle oddle oo I ey, toddle oddle oddle oddle oo I ey
Now, I decided to wonder way the country to explore

Second verse
Well, I had not long walked when there beside the ocean
I saw something move, like all the world in motion
Now I creep up beside the thing, it was a great big crocodile
From the end of his nose to the tip of his tail was about 500 miles, yes about 500 miles
So I sang, toddle oddle oddle oddle oo I ey, toddle oddle oddle oddle oo I ey
From the end of his nose to the tip of his tail was about 500 miles

Third verse
Now I could plainly see this was none of the common race
For I had to climb a tall tall tree before I could see his face
The wind was blowing so hard up there, it blow with a gale form the south
and I lost my grip on the big tall tree and fell smack dab in the crocodile's mouth, yes smack dab in the crocodile's mouth
So I sang, toddle oddle oddle oddle oo I ey, toddle oddle oddle oddle oo I ey
I lost my grip on the big tall tree and fell smack dab in the crocodile's mouth

Fourth verse
Now I could see this crocodile was going to nab a victim….. me !
so I ran down his throat you see, and that's the way I tricked him. see?
Now I wandered around for a year or two, until I reached his craw (that's his stomach)
There was a rum case, not a few, and a thousand pullets (little chickens) in store in store, a thousand pullets in store
So I sang, toddle oddle oddle oddle oo I ey, toddle oddle oddle oddle oo I ey
There was a rum case, not a few, and a thousand pullets in store"

Final verse
Now the crocodile grew very very old and at a great long last, he died
It took him about six months to catch a cold he was so long and wide
His skin was about 10 miles thick, I think, or some where there about
For I was fully six months digging my way out, yes digging my way out
So I sang, toddle oddle oddle oddle oo I ey…, toddle oddle oddle oddle oo I ey
For I was fully six months digging my way out
and I got out just in time to come here and sing this song for you!
