New York City has never been the same since. Millions of residents are being coaxed back in from their fire escapes after the sheer terror of these handmade Halloween sweaters.
Babs unleashed her terror on the city by sending her son there with a batch of bats for his friends. This is what happened.
First of all, the Brooklyn Bridge was so terrified it broke out in rust.
Then the Statue of Liberty tried to fade into the background.
Pumpkins that started off huge...
Withered and shrank with fear ....
To mere shadows of their former selves - just lunchtime snacks for Bertie Bat.
When night followed day, Bertie Bat came out to play.
And champagne lounges are just the beginning. Because Bertie had his eyes set on higher things...
Yep, other people's drinks on rooftop bars.
After a heavy night of fear-mongering, Bertie took it down a notch and spread a bit of gentle unease along the High Line.
Then he finished his trip off with some relaxing marrow chilling at Dylan's Candy Bar.
With just $100 or so of candy to occupy his fangs and keep them off New Yorkers' necks.
Bertie Bat is now back in England, but his friends are still at large in New York. They were last seen flapping their way across the Hudson, through Battery Park north towards Soho. Keep safe, New York, keep safe.
Have your own adventure in one of Babs' ghoulish garments. Warning: they do make you act alarmingly.
