The Rodriguez Brothers Circus is in town! Every year, the circus arrives and stays for a week.

Then they go to the next town.There are not many animals in the circus. People told the circus

that they didn't like seeing animals performing. There is an elephant called Jacob and two old

lions, Hattie and Meg.Most of the performers are human! There is Leopold, The Strongest Man

In The World. His father also worked in the circus, but Leopold is stronger than him, he has

bigger arms and bigger legs too! Leopold performs his act every night for the town's people who

come to watch.

Another performer is Clara. She says she has the longest hair in the world. It's about 4 metres

long! She also has a daughter who works in the circus. Her name is Sue-Ellen. Her hair is a lot

shorter, but she wants to grow it as long as her mother's. Sue-Ellen helps look after the animals

and she's also learning how to juggle.

The stars of the circus are the three clowns, Pit, Pot and Pat. They all wear long red shoes, but

Pat's shoes are the longest and sometimes, he falls over because they're so long! They perform

for about twenty minutes and they are always the most popular act with the audience, especially

the children. Many people think Pit, Pot and Pat are three brothers, but Pat is older than the other

two - he's their father! He's the oldest clown in the country, but he has a lot of energy.
