The frog was hopping around the lab.
Tom tried some more magic spells.
But nothing worked.
"What about a potion?" Cat asked.
"Good idea, Cat," Tom said.
"I'll try to turn that frog into a dog."
Tom mixed some potions.
But none of them worked either.
The next morning there was still no dog.
Tom sighed. "I better think of something fast.
The birthday party starts soon."
Tom watched the frog hop around the lab.
It hopped near a stack of books.
"Hey!" Tom said. "Those are old spell books."
Tom flipped through the spell books.
"Here’s a dog spell!" he said.
"The queen wants a special dog," Cat reminded him.
Tom lifted his wand. Poof!
A dog with wings appeared!
"I did it!" Tom said happily. "It's a flying dog!"
Cat hid in Tom's pocket.
The dog flew all around the room.
"Wizard!" Dirk banged hard on the door.
"The party is starting."
Tom whistled.
"Come on, Dog. It's time to go."
The dog didn't listen to him.
"Come on, Dog!" Tom said again.
But the dog stayed in the air.
Cat peeked out of Tom's pocket.
"Woof! Woof!"
The dog flew right down at Cat!
