YOU SAID:
His body is like a huge lump of dough that is fed by the thoughts and stories of the books
INTO JAPANESE
彼の体は、本の思考や物語によって食べられる巨大な生地のようなものです
BACK INTO ENGLISH
His body is like a huge fabric that can be eaten by the thoughts and stories of books
That didn't even make that much sense in English.
