Mr. Sludge, the medium-sized snail,
Wherever he went, left behind him a trail.
Now, trails are to snails as a caw's to a crow.
You can find them wherever they go.
Mr. Sludge, Mr. Sludge.

Mr. Sludge had a very large wife
Who followed him everywhere most of his life.
One day he went down to the doctor to see
If he had any trail remedy.
Mr. Sludge, Mr. Sludge.

Doctor said, "now look, Mr. Sludge.
Your tail helps to guide; otherwise you won't budge.
I'll give you a liquid called cystal cordide.
Drop it behind you when you want to hide."
Mr. Sludge, Mr. Sludge.

Mr. Sludge, the medium-sized snail,
Wherever he went, left behind him a trail,
Except when he felt like a snail holiday;
Then where is he? No one can say.
Mr. Sludge, Mr. Sludge.
