Soiled Doublets

Lewis Carroll:

I enclose some Doublets, with which you may like to occupy your free minutes (if you have any). To solve a Doublet, you must change one letter only, in the first word, making a real word; then change one letter only in the new word, and so on till you get to the second word. The intermediate words are called "Links," and the whole thing a "Chain."

An example, from rice to poop, from BigHominid's Hairy Chasms:

PACE
PALE
POLE

POOP

A further example by my son (Turdman Junior, a chip off the old block), transforming bean to fart:
