Lyrically, the ballad employs several "twist and turns", using very specific lyrics to describe both the performer's fascination with the human world and desire to walk among them, including "walking around on those what-do-you-call-them?... feet" and "Up where they walk, up where they run/Up where they stay all day in the sun/Wanderin' free, wish I could be/Part of that world." Comprising "impeccable rhymes" while incorporating the term "thingamabobs" into the line "You want thing-a-ma-bobs? I've got twenty but who cares? No big deal, I want more", "Part of Your World"'s "empowering" lyrics convey several messages, such as facing one's fears, believing in oneself, and wishing for new life experiences. The ballad concludes with a final chorus belted "When's it my turn? Wouldn't I love, love to explore that world up above? Out of the sea/Wish I could be/Part of that world".
