“Pretty Little Ditty” is an instrumental track composed by bassist Flea and guitarist John Frusciante.

As one of the best examples of the eclecticism the Red Hot Chili Peppers experimented with, it is one of the few songs on Mothers Milk to feature no guitar layering. Music journalist Jeff Apter described the song as:

A dreamy, sweetly stoned instrumental featured deft picking and strumming from John Frusciante, intertwined with blasts of trumpet from Flea.

Crazy Town famously sampled a portion of the song in their 2000 single, “Butterfly.”
