Bad day
In the horrible school there was lots of howling.He was very frightened about what was going on.Suddenly he realised it was ugly trolls.He saw a machine. It said make the horrible school and ugly trolls disappear.He pressed the button on the machine.Then the school and the trolls disappear.He was very happy that the scary things got away.He never went there again.
Who was frightened? How did the school disappear?
I like in the beginning you said howling
Show not tell.
You could have described the button.
Use more details .
I like that there was a machine that could make the ugly trolls disappear I really enjoyed it!
Where did you go after the ugly trolls disappeared?
Maybe you have to add comma then you write a sentence.
