it just hit me that since one line in “Abracadabra” is “These are the words I hum to myself,” at least part of the song is something Pluto made up while standing at the Doors of Time alone of thousands of years.

She hummed to herself to pass the time and to feel less alone.

Now she has one little princess to share the tune with.

I love Pluto and Chibiusa so much you guys.
