Queso means

and I were talking about something, i don't remember what but she didn't know what 'Queso' meant.
So poor Bekkah was confused but little Amai, Nukui's younger brother, is there to help. Holding up is big slice of cheese and singing the chesse song!

The Chesse Song lyrics:
Chesse, Chesse.
It's yellow, it's square, it's healthy.
Chesse, Chesse.
It's better then meat, it's dairy!

It was orginally suppose to be Nukui's asking, which explains the dialog, but i changed it to Bekkah since asked.
