The king called Tom to the Throne Room.
"Princess Mary has disappeared!" the king cried.
"I'll find the princess!" Tom said.
He waved his wand. Poof!
There was a puff of smoke.
But nothing else happened.
"Oops," Tom said.
"Wait . . ." Cat sniffed the smoke.
"It smells like trees and moss," she said.
"It smells like the Dark Forest!"
Tom gasped and looked at the king.
"Princess Mary is in the Dark Forest!" Tom said.
"What?" The king turned pale.
"The Dark Forest is dangerous!" he cried.
"We must find the princess at once!"
The king called his knights and guards.
"Search the Dark Forest now!" he said.
"Find Princess Mary!"
The knights and guards crashed through the Dark Forest.
They called loudly for the princess.
But they couldn't find her anywhere.
Finally they returned to the castle.
"Wizard!" the king yelled.
"You must find the princess!"
Tom gulped.
"Yes, Your Majesty."
"I used to live in the Dark Forest," Cat said.
"Follow me."
Tom followed Cat into the Dark Forest.
They looked all around.
"There!" Cat said suddenly.
Tom saw footprints on the ground.
He saw some hoofprints too.
"Princess Mary is with the unicorn!" Cat said.
