Hodor the hippo has been introduced at Whipsnade Zoo, around a month-and-a-half after being born.

The baby hippo weighed about 30 kilograms at birth (about the same as an adult Labrador according to the zoo) on July 21.

According to zookeeper Angela Robinson, Hodor is a playful hippopotamus who: “Has taken a liking to winding up his mum by chasing and play biting at her tail.”
