The Rhino

It was a sunny afternoon. Anne and Rex decided to walk to the zoo to see some rhinos. They went to the rhino den.
Anne said, " I am going to take a selfie with the rhinos."
"Oh no, you don't," said Rex, "you will fall in."
"Well, I am going to take a selfie if you like it or not."
So she leaned back. 
Bang!! She dropped her phone. It hit her chest and down she went into the rhino den.

"REX HELP!!!!"

"Do not move!" said Rex, "or they will charge, and with one swipe of the horns, it will be the end."

"What do you mean by the end?" said Anne.

"You do not want know," he said . "I will go and find  a zookeeper."

"NO!! I will get in trouble if you do," she said. 
"OK. What should I do?"
"Go find a rope," said Anne, so Rex set off to find a rope. He looked everywhere but not in the zoo keepers' staff  room.
"I am going to have to sneak in," he said to himself. “Oh no, the door is locked, but a window is open.” 

He walked over to the open window and climbed inside. He looked on the soft old chair and found a long green rope. He quickly grabbed the rope and ran to his sister. "Here is the rope." 
He threw the rope down to Anne. She climbed out. 
"Thank you, Rex, you saved me. Let's go and get chocolate ice cream and forget about the incident."
