Have we got a show for you!!"If you like to talk to tomatoes
If a squash can make you smile
If you like to waltz with potatoes
Up and down the produce aisle . . . ."
Has Mazie been watching too much Veggietales?

Possibly. Her nightgown is black, so she's calling herself the BLACK tomato. Reminds me of the Scarlet Tomato from Larry Boy and The Angry Eyebrows.
