Here is the completed text with the correct forms of 'there was' or 'there were':
When I was a girl, I lived in South Africa. Around my house 'there wasn't a lot to do but there were lots of animals to see because we lived next to a wildlife park. In my bedroom there was a big window, and in the mornings, I could see there were lots of animals. There were hippos in the water and there were enormous elephants sleeping. There was always a big giraffe next to a tree and a strange bird sitting on the tree that looked angry! My favourite animals are tigers, but there aren't any tigers in the wildlife park. That's because there are no tigers in South Africa.
