The Zoological Society of London’s Whipsnade Zoo has released adorable footage of the newest member of its family, a male pygmy hippo calf.

The baby’s mom, 28-year-old Flora, gave birth on Boxing Day and had a smooth pregnancy even though she has been battling cancer.

In the clip, the animal mostly pals around in the hay with his mother and goes for a swim.

Senior keeper Steve White said in a statement: “On his first weigh-in, he was so slippery it was like picking up a big bar of soap!” The zoo also says the animal “is a particularly welcome addition to the Zoo because there is a shortage of male pygmy hippos within the European Endangered Species Breeding Programme.”

In September, a pygmy hippo named Olivia went viral because of her striking resemblance to the Michelin Man.
