Song
Strums it's vocal cords, making a small, faint guitar sound. At the end of the song, it goes crazy. It starts to change from melody, to environment song. It rapidly strums and wails. In it's revamped mode, it actually talked, but in a very gargley tone.

Origin
It is possible that the blue skin is a reference to Blue Baby from The Binding of Isaac series.
