Bathilda

When they say she’s an old bag of bones (they’re two thirds right)
When they say she’s long in the tooth (it’s because of the fangs)
When they say she’s a ripe old age (it’s because of the smell)
When they say she’s no spring chicken (because the snake ate ’em)

A decorated historian
A hero to Hermione
Someone that we’d really like to talk to
Now but she’s just a human sack for a snake

She’s a sack for a snake
(she’s a snack for a snake)
