I cure a bellyache without a spoon, When mixed just right, I change the tune. A coconut’s best famous friend, Sing it once- the chorus won’t end. What am I?

Perfectly plumed, this prickly peer perceives private phrases, Practicing precise parodies that provide profound perplexity. Partially pampered, partially pest, it pursues petty pieces, Pacing its perch, preaching platitudes with pointed persistence.
