Douglas, the hippo calf is seven months old and was found wandering alone near the Zambezi River. The little fella takes a shine to Paul and follows him around like a faithful dog – even going for a paddle in the pond together – aww!
Paul then meets a baby giraffe who's been abandoned by her parents and the presenter gets to give her a bottle, but discovers that's not an easy task…
Wendy the warthog and PJ the vulture chick also melt his heart, and finally Paul gets to spend some time with his favourite baby elephant Nakala.
