She chats with a gnat, who is her small friend.

One day, Sarah heard an echo while she was talking to the gnat.

The echo came from a ghoul who lived in a castle nearby.

"Sarah, don't be scared. Listen carefully," the gnat said.

"The ghoul just wants to wrestle with his problems," explained the gnat.

"Let's help him. Fasten your courage, Sarah," gnat added.

Sarah agreed to help the ghoul.

They went to the castle and met the ghoul, who was a chic chef.

"He wanted to cook but didn't know the chemistry of food," the gnat whispered.

"Sarah, let's practice cooking with him," suggested the gnat.

And so they did, turning the castle kitchen into a happy whistle of activity.
