If you're having a hard time figuring out what's being said:
Tina: "Naomi, what comes out of a volcano?"
Naomi: "Hot Blabla."
Tina: "Can you say it again?"
Naomi: "Hot Blabla."
I'm not sure how lava has turned into blabla, but we can't convince her that she's saying it incorrectly. Oh well, it's cute!
This is a song she learned in school today. Earlier there was something about sending her frown towards heaven so it turned into a smile, but she seems to have left that part out. I think she improvises sometimes.
