Quite write: Gertrude.

In writing , the task we had to do was write a quick story based on a picture for 10 minutes.We had to include these five words: Fun , run , unicorn , Billings and santa. The focus was getting ideas down. The picture we had to write about was a big explosion and a pile of old cars , with people far away from them. 

The blue coloured words mean that they are the words we were supposed to use.  

This is my writing so far: 

While Mr billings was riding his pink unicorn away from the fire explosion , and the big pile of cars , he saw santa and his unicorn, gertrude went crazy. He loved santa. But the only reason gertrude liked santa , was because santa was quite overloaded.

Now you see , gertrude wasn’t type of normal horse , he could stand on his back two legs for ages. Poor santa had to have an issue with being kicked around like a really large soccer ball. Santa never liked gertrude , once he was running away from him and gertrude thought this was a fun game.
