Pig On A Swing by Jenny Nimmo
When Tim and his mum went to the playground no one was there. Tim couldn't play all alone. He said, 'I want to go home.'
'Wait,' said his mum, 'I think I can see - what can it be, sitting on a swing?'
Tim looked at the swings. What was there? Was it a pig? Yes, a little pink pig sitting on a swing.
