The Twits: Level 4

Mr and Mrs Twit are bad people.
Ugly Mrs Twit likes playing tricks on Mr Twit, and hitting animals and children with her stick.
Mean Mr Twit glues birds’ feet to trees, and make poor Muggle-Wump the monkey do tricks upside down for hours every day.
One day, the Roly-Poly bird arrives. He wants to help the monkeys.
Can the animals turn the terrible Twits upside-down?
