This baby certainly looks like one happy hippo as she settles into life at the zoo.
The female calf was born two months early at the Cincinnati Zoo and required critical care to make it through her first weeks.
Weighing a mere 29lbs, she was 25lbs lighter than the lowest ever recorded birth weight for a Nile hippo, making her a record breaker from day one.
While staff were originally worried that little Fiona would not survive, she is now going from strength to strength.
Pictures show the happy little hippo guzzling from a bottle, snoozing through a medical check and getting used to splashing about in the water.
She is gaining her strength up before she can join her parents in the outdoor enclosure, but staff say she is already toughening up.
A zoo spokesperson said: “She’s grown into a strong and sassy hippo!
“She now weighs more than 200 pounds and has figured out if she doesn’t want to do something, all she has to do is sit down.”
