I'm a little stuck... Click here to teach me more about this clue!

'the simpleton' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for noodle that I've seen before include "Fool (in the soup?)" , "Ribbon-like strip of pasta" , "Simpleton; piece of pasta" , "Blockhead" , "See silly person" .)

I've seen this clue in the Evening Standard.
