The Dirty Kid
Each clue leads to a word from a particular nursery rhyme (all found online). There are five words for each rhyme -- two rhyming pairs, and a fifth word. Find the word that rhymes with each unrhymed word.
("Little Bo Peep")
("One Stormy Night")
("Who Killed Cock Robin?")
("An Alphabet of Names")
The five words LIGHT, NIGHT, KEEP, PEEP, and DARK all appear in "The Little Star" (a longer version of "Twinkle, Twinkle Little Star"), so, doing the happy-recursive thing, finding the rhyming word for DARK gives the answer, SPARK.
(NB: "Dirty Kid" clues, extremely obliquely, "Uncouth Youth".)
