The boy tried to 3 the magic words. He tried "open" "hurry", and many more, but none of them worked.
Tired and upset, the boy 4 out, "This is too difficult. Please, dear tree!" Suddenly, a big 5 opened at the bottom of the tree. He came in. Inside everything was 6 . He couldn't see anything except for a sign. The sign said, "Carry on with your magic." Then the boy said, "That is a good idea. 7 , dear tree!" With this, the inside of the tree lit up 8 and showed a road. The road led to a 9 full of toys and chocolates.
The little boy brought all his friends to the magic tree and they had the best party ever in the room. This is why people always say that "10 " and " thank you" are the magic words.
