Bubbles is known as the most popualr and prettiest girl in the school, which ironically due to the amount of fanboys and love letters she gets that fills her locker, she is completly unaware of it.

Bubbles is very caring, but has a more grown up tone in her voice.

I think it would be interesting to see how a Tara Strong voice would fit her, but you can use her original by Tara Strong or her Z voice Maryke Hendrikse.
