Gourd (5)
'gourd' is the definition.
(I know that melon is a type of gourd)
This is all the clue.
(Other definitions for melon that I've seen before include "Gourdlike fruit" , "I'm very seedy" , "Honeydew fruit" , "Large vine fruit" , "Edible gourd" .)
(Other definitions for noodle that I've seen before include "bit of pasta" , "Simple person - in the soup?" , "strip in the kitchen" , "Narrow strip of pasta, or foolish person" , "In slang, a foolish person or just the head" .)
