At Kati's vet, Ryder was waiting for Kati to finish cleaning the collar so she can have a better look at it. Then the pups ran in, and Kati walked out.

"O my." Kati said as her and Ryder saw Marshall walking in.

"Marshall what happen to you?" asked Ryder.

"We can talk about Marshall getting beaten up by a mud puddle later, but he might know where the thief went." said Rubble.

"I didn't get into a fight with a mud puddle, but I saw something that might help us." said Marshall.

"Well it looks like you got into a fight." said Rocky. Marshall gave Rocky a evil look. "Sorry" he said and smiled at Marshall. Then Ryder's pup pad went off.

"Hello Ryder here."

"Hi Ryder, its me . I have a small problem. Someone took all my carrots."

"Wait we were there, but we didn't see any else there." said Skye.

"Yea once Rocky drove past us, we got into our rides and headed here." said Rubble.

"Okay so maybe we might have to find this guy at night." said Ryder.

"But where will this person go next." asked Chase.

"Yea, the person been to Jake's Mountain, Farmer Yumi's, and Cap'n Turbot." started Marshall.

"Dude don't forget 's place also. Where else will there be food." said Zuma. They started thinking, until Marshall made a face.

"Here and the Lookout." he said. They all looked at him.

"What do you mean Marshall?" asked Rubble.

"Kati has food here, and we have food at the Lookout. Whoever is taking the food might hit here or the Lookout maybe both." said Marshall.

"He's right." said Chase.

"Dude did the mud you were fighting with give you some brain juice, or some brain power." laughed Zuma.

"Okay guys tonight we are going to get to the bottom of this. Chase and Rubble you two will stay here with Kati. Rocky, you and Zuma will be at the Lookout with me. Marshall you will be by the forest where you saw the thief and Skye will be with you. We are going to catch this person."

That night, the Paw Patrol were all at their spots. Kati made all of them black sweaters. Chase was in deep thought, and Kati saw his face, he looked worried like he does when Skye does something dangerous.

"Chase are you alright?" she asked. Chase didn't answer. Rubble wanted to him and waved his paw infront of Chase's face, but Chase's wasn't planning attention. Kati put a dog treat by his nose but sadly that didn't work.

"Kati come in this is Ryder."

"Hey Ryder whats up?" she said.

"How are things there?"

"Everything is good, but Chase is not acting like himself."

"Why do you say that? Whats wrong with him?"

"I don't know, he is looking at the window, and is in deep thought. Me and Rubble try to get his attention but nothing is working."

"Okay thats not him,...Kati I will chat with you later. I think who is stealing food is here." Ryder hanged up. Kati walked back to Chase who was moved from where he was standing to his hiding place. At the Lookout Ryder, Rocky and Zuma were all hiding. They saw a shadow, and it took most of the pup treats that were there. Rocky set the trap off, but it didn't catch the thief. Once the thief ran off, Ryder and the two pups started to follow it, but Rocky's trap landed on top of Rocky and Zuma.

"I hate it when my traps back fire at me." said Rocky with a big frown. Then he got up and him with the help of Zuma were trying to get the net off. Ryder was outside on his ATV on his way to Kati's. Once Rocky and Zuma got free, Zuma hopped in Rocky truck and Rocky drove off at top speed. They got to Kati's and saw that the thief was there, but left so Rubble was in Chase's police truck. Kati got on Ryder's ATV and sat behind him. They drove off the followed the thief.

"Dude whoever this person is they run fast." said Zuma. Ryder tapped on the pup pad.

"Marshall, Skye the thief is on his way to you guys, so be ready."

"You got it Ryder!" said Marshall and Skye. They both hid behind Marshall's firetruck.

"There he is." said Skye. So they both jumped out.

"Stop right there!" they both yelled. The thief stopped. Then Ryder, Kati and the rest of the team popped up, and they surrounded the thief. When they got closer they all saw that the theif wasn't a human like they all thought. It was a pup.
