After leaving Sky and Rocky, Ryder and Zula had made their way to the cell block through the air shafts.
"According to Razer and the others, he should be on this level," said Ryder as they passed empty cells after empty cells.
"He's three cells down on the right," said Zula as she picked up on a familiar smell while leading the way.
"Zula, what are you doing here, and who is this?" asked a Puptillian who was being held in one of the furthest cells in the back.
"I'm here to get you out, Zuka; and this is Ryder, leader of the Paw Patrol," said Zula as Ryder got to work on picking the cell lock.
"Guess that means we're in Earth's system," said Zuka as Ryder opened the cell door and let him out.
"You are, are your sister has been a great help in filling us in on what's happened with the Catarlas," said Ryder.
"We have also discovered that a bacteria has infected the Catarlas, that's why they are after the powerstone since it can heal them," said Zula.
"Are you being serious right now?" asked a surprised Zuka as he looked at his sister.
"We have a cure and plan to introduce it into the air, so they all can be given one dose," said Ryder before contacting Sky and Rocky.
"We got Zuka, how are things going on your end?" asked Ryder.
"We're ready to go whenever you are," said Sky as she and Rocky pressed a button on the puptags to cause masks to appear on their faces.
"Go ahead," said Ryder as he, Zula, and Zuka climbed into the vent with masks to cover their mouths and noses so they did not breath the cure in.
