This is a big birthday weekend for a big girl from Cincinnati!
Fiona the hippo is turning 4-years-old!
Fiona's birthday is Sunday.
She was born 6 weeks premature, weighing only 29 pounds and unable to stand.
Now, she's a whopping 1,500 pounds and ready to party.
The Cincinnati Zoo is hosting a Float for Fiona Apple Race this weekend to raise money for their zoo.
It will all be streamed on the zoo's Facebook page.
Happy birthday, Fiona!
