Tom walked around his lab.
"I must help Tink," he said.
Just then Ann rushed in.
"The king said to come quickly!" Ann said.
Tom and Cat ran outside.
A crowd was gathered at the wall.
Water poured from a crack.
"Tink was looking at that crack!" Tom thought.
"Do something, Tom!" Dirk cried.
"I have an idea," Ann said.
She handed gum to each person. "Chew!"
Everyone chewed.
Cat ran to the Grim Dungeon.
"Now throw your gum at the crack!" Ann said.
Everybody threw.
The gum plugged the crack.
"It's working!" Tom said.
Then all the gum fell off.
The leak got bigger!
"Wizard!" said the king.
"Fix it now!"
Tom pointed his wand at the crack.
"I wish—" Poof!
Fish appeared.
"Oops," Tom said.
"Do something, Wizard," Dirk yelled.
"Or join your friend in the Grim Dungeon!"
Tom closed his eyes.
He waved his wand, and . . .
Tink and Cat appeared!
"I can fix that leak!" Tink said.
Soon water stopped pouring from the crack.
"Tink is a bad jester," said the king.
"But he's a great tinker!"
"Good work, Tom," said Ann.
"You saved the day!"
Tom felt proud.
And so did Cat.
