Jack was devastated. He sniffed loudly and squinted through his tears as he attempted to tape a lost pet poster to a nearby bus stop pole.

Earlier that day he and Maddie had been carrying groceries into the house when Cujo zipped under their feet and out the front door. The green pup yipped happily as he darted across the street, paused long enough to turn his head, ears perked upward, and then dash down the sidewalk.

Jack and Maddie tried to chase after him but he disappeared around the corner and they had no idea if he had actually turned invisible or had simply left their line of sight.

Jack immediately started to panic. Maddie had to remind him that as a ghost Cujo was not in danger of getting run over, or kidnapped. She didn't mention that she was more worried about him feeling threatened and reacting aggressively.

After an hour of searching, they returned home to get their ghost tracking equipment and to let the kids know what had happened.

…

Danny was at the Nasty burger with Sam and Tucker when he got the call. He immediately stood up and excused himself.

"Wait, Danny," Tucker shouted, "I have that ghost tracking app on my PDA. We could help look."

"I'd really appreciate that," Danny said, standing halfway out the door. "Call me if you find him."

Sam and Tucker nodded as Danny hurried into an ally to transform. Once he was in the air he pulled out the dog whistle and started blowing on it. No response. Maybe Cujo went to the park. They usually went that way on their walks.

Danny barely looked around to make sure no one was watching before changing back into his human form. The park was surprisingly empty, which hopefully wasn't because a massive ghost dog had just hurried through.

Danny blew the whistle again and then called out. He waited a few minutes and called again. Still nothing.

Danny hurried to the park gates and started tracing the path he and Cujo usually took. With any luck, neither Valerie nor any other ghost hunters would be around and someone in his family would find the little green pup before he got into any real trouble.

…

Danny had made it home without so much as a flicker of Cujo's glowing tail. He tried to think where else the dog might go. Normally he'd try the ghost zone but if Cujo ran outside the house then the ghost barrier would prevent him from getting back in. Danny would just have to keep looking.

Occasionally he'd get a text from his parents, Jazz or Tucker, asking if he had any luck, but his response was still no. He frequently checked the local news in case there were any sudden ghost watch reports covering green animals. The only thing that came up was the box ghost and a few unconfirmed sightings of green blobs. The box ghost one didn't seem serious so he decided to take care of it later.

Danny started checking side streets and allies as he called out and blew the whistle. Cujo couldn't have gotten too far, but then again he was a ghost. He could be in the next state over by now for all they knew.

Danny circled back to the park nearly a dozen times with no luck before collapsing onto an empty bench. He needed a moment to think, maybe he missed something, or maybe Cujo had snuck back into the house when no one was looking. He could be safe at home and they didn't even realize it.

Yip

Danny's head shot up.

woof

Danny stood and looked around. He didn't see any dogs, green or otherwise. Maybe Cujo was invisible. That would be a laugh. If the dog had simply been invisible this whole time and following at his heels, but then why wait until now to make any noise?

"Up here, kid."

Danny looked up and he caught sight of a bright red jacket and skirt accompanying a mess of green hair and leggings to match.

"Kitty!?" Danny replied in surprise before realizing she has a squirming ball of glowing fuzz collected under one arm.

Kitty landed swiftly and held the delighted dog out in front of her for Danny to take.

"I believe this is yours."

"Uh, yeah," Danny was trying to process his surprise. "Thank you. Where-"

"Gas station just off the highway." Kitty interrupted. "I think he followed a hot dog truck there."

"Oh…" Danny hoped that was all he did.

"Word of advice," Kitty snapped. "Stay away from Johnny for a few weeks."

Danny didn't want to ask but decided he had to. "Why should I stay away?"

"Your pup there lifted his leg against Johnny's bike, which was bad enough while he was small, only Johnny tried to pick a fight and...well the next time he lifted his leg he wasn't so small."

Danny cringed. "I am honestly sorry that happened."

Kitty eyed him for a bit before deciding he meant it and relaxed her stance. "Just keep a better grip on the mutt."

Before Danny could respond she took to the sky and disappeared.

Danny glanced down at Cujo who excitedly tried to lick his chin. "You're lucky you're cute," Danny sighed before pulling out his phone to let everyone know Cujo was found.
