Who is Naughty Grandma?

WHO is Naughty Grandma, you might ask?
She's the most bad (beep) Grandma you'll ever see.
She has a teenage grandchild she hates with all of her fragile, creaky heart,
And a husband who is just as rotten as she.

Who is Naughty Grandpa?

He is the sweet husband of Naughty Grandma. He is just as cold hearted as his loveable wife. They are always fighting about one thing or another. Mostly about why they don't kick their ridiculous grandchild, Brunhilde out of their house.

Who is Brunhilde?

The grandchild of Naughty Grandma and Grandpa. We now know why they do not like her.
