Charlie and Itchy have been given jobs to serve as night guards. Their first night is to guard an amusement park. They had strapped on hats and belts Carface had given them.

"Well, our first night to guard the amusement park," Charlie said. "This could be fun."

"I don't know, Charlie," said Itchy. "Night duty can be scary."

"What are you worried about? There's nothing to be afraid of. Sure, the amusement park is closed, but that's part of the fun when doing night duty."

"To you, it's fun. Me, it's just scary."

"Enough chitchat, you two are to start the night duty," Carface said. "That reminds me, you'll need these." He held out a pair of diapers.

"Wait a minute, why do we have to wear diapers?" Itchy asked. "I don't get it."

"Uh, I'm with Itchy on this. I don't think it's necessary," Charlie said.

"You'll be needing diapers to stay busy," Carface said. "Your belts have pouches that contain spare diapers for when you need a change. And besides, wearing diapers for night duty is mandatory."

"Mandatory? Carface, I don't think..."

"I did not ask for any of your opinions, Charlie," said Carface, cutting him off. "Alright, good luck." He then left.

Charlie and Itchy sighed, as there was no point in arguing with Carface. So they threaded their tails through the diapers' tail hole and held the fronts on their groins, and they taped the sides.

"Well, I guess this is where the night begins," Itchy sighed. "Me and you, guarding the park, wearing our diapers."

"Yeah, I think what Carface said might be a valid point," Charlie said. "Let's go."

The two entered the amusement park and began the night shift, as they pulled their flashlights from their belts and started patrolling. As they patrol, a small creature emerged from a trash can. It was a rat wearing clown makeup and a bowl hat with a word "Pranx" on it, as it was the rat's name. The rat saw Charlie and Itchy on night patrol, and he decided to have some fun.

"Okay, Itchy, you go this way, and I'll go that way," Charlie said.

"Be careful, Charlie," said Itchy.

The two went separate ways.

Charlie past by a few game stands, as he noticed a few of them dirty. "Huh, they didn't bother cleaning a few stands here," he huffed.

Charlie walked on as Pranx was nearby, hiding behind a water tank as he walked by. Charlie stopped to look around, as Pranx grabbed a hose and snuck toward him. The rat climbed on the tank and stuffed the hose into Charlie's diaper, just before Charlie walked away. Pranx watched him walk away, and then he crawled to the wheel and turned on the water.

Charlie walked on and looked to the side, as the water traveled through the hose and began filling his diaper. He walked on, unaware of his diaper filling with water, and it grew big as he waddled, his diaper sloshing. He flinched when water trickled down his legs, shivering from the cold water. "Ooh..." he shuddered, before looking at his bloating diaper. "What's going on here?" But he paid no heed and waddled on, as his diaper grew bigger and bigger, as it finally lifted him off the ground. He kicked his feet, and then his diaper exploded with a loud pop, and he hit the ground, splashing on a puddle, as he then got up, shaking himself dry. "Brr. What was that?" He took out a spare diaper and taped it on.

Pranx tittered at the prank he had done, and he ran off.

Meanwhile, Itchy was walking past a carousel, shining his flashlight on the horses. "Nice ponies," he said, admiring the colors. "Those humans really spent a lot of time on their hands." He scratched his diaper butt. "Ah! My butt's itchy!" He groaned as he scratched more, and he sighed. "Alright, Itchy, just focus on your night shift."

Pranx saw Itchy and ran as he hid under an ice cream stand. Itchy walked on as he walked by the ice cream stand. He walked and looked around, as Pranx climbed up the stand and grabbed a hose, as he snuck behind him and tucked it into his diaper, and he crawled to the ice cream machine, attaching the hose to a spout, and when Itchy walked off, the rat turned the nozzle, as the ice cream traveled through the hose and began filling his diaper.

"Ah!" Itchy yelped. "So cold!" He shivered as diaper grew bigger and touched the ground. His teeth chattered as the ice cream trickled down his legs, and he looked down, seeing his diaper growing bigger. "Ooh! Charlie! My diaper's getting cold!"

Itchy's diaper then exploded and spilled ice cream all over the ground. "Oh, jeez. What was that about?" He wondered, as he cleaned his bottom, pulled out his spare diaper, and taped it on.

Pranx giggled at the prank he did and ran off. But his prank playing on the two had only begun.

The night went on, as Charlie and Itchy went to check a few food stands. Pranx had set up a plate and filled it with cheese and sausages, even prunes, in toothpicks. He placed the plate on a stand and ran off, hiding under the carousel.

"Hey, look, Itch," said Charlie. "Somebody's left us these snacks."

"I don't think we should eat those, Charlie," said Itchy. "Something tells me this isn't a good idea."

"Come on, Itch, a little snack wouldn't hurt."

"It's not that. I have a feeling this might be a trap."

Charlie looked at Itchy and then said, "Well, I'm gonna eat it. Bottoms up." He grabbed a snack and ate it. "Not too scared, are ya?"

"Me, scared? No! I'm gonna have a snack with you!"

Itchy and Charlie ate the snacks until the plate was empty.

"Was that so bad, Itch?" Charlie said, patting his tummy.

"Nah, not so bad," Itchy said.

Oh, but it was about to happen as soon as they walked off to continue their night duty. An hour ticked by as they walked. Their eyes widen when their bowels rumbled from the prunes they digested.

"Oh," Itchy groaned, gripping his belly as his bowels rumble. "What's happening?"

Charlie grabbed his diaper butt as his bowels gurgled more. "Nnff... I don't know, Itch, but I think I have a bad feeling!"

Charlie and Itchy's bowels rumble more as they groan. Then they began messing and filling their diapers a lot, groaning in pain. Tears slid from their eyes. Their bowels kept rumbling and filling their diapers as they grew bigger, and the messing stopped above their feet.

"Oh, my stomach hurts," Itchy groaned, rubbing his belly.

"Ow...it must've been those snacks we ate," Charlie said.

"I told you, Charlie, but you didn't want to listen and had to get me eating them. Ow, I'm gonna feel that in the morning."

As Charlie and Itchy cleaned up their bottoms while changing their diapers, Pranx peeked from under the carousel and looked at the haunted house ride. He smirked at the two, as the little rascal has one more trick to pull. He rushed into the ride and flipped the switch, turning on the ride.

Charlie and Itchy were alerted after changing their diapers, as they turned to the ride.

"Hey, the ride's not supposed to be on after hours," Itchy said.

"Yeah, someone must be here. Come on!" Charlie said.

The two ran into the ride, as Pranx hid behind a tombstone decoration, snickering.

Charlie and Itchy went to check for anyone, as they approached a cart.

"Wait, we're not taking rides, Charlie," Itchy said. "Even I won't like this haunted house ride."

Charlie gulped as he said, "I think you're right, Itch. Let's go back."

But Pranx wasn't gonna let their departure spoil his fun. He grabbed a few bats with strings and climbed up a wall, and he held them hanging by the door. He shook and tugged the strings to create the motion of the bats flying. Charlie and Itchy saw them and yelped as they scurried backwards, but they tripped and fell in the cart, as the lap bars lower down on them.

"Oh, no! Charlie!" Itchy cried, as he and Charlie struggled to lift up the lap bar. "I can't lift it up!"

"Nngh! Neither can I, Itchy!" Charlie grunted.

Pranx ran to the lever and pulled it down, as the cart took Charlie and Itchy for the ride of their lives.

They went through a dark room filled with glaring eyes in shadows and a coffin, as it opened, and out came a roaring mummy. The two yelped in fright as they entered another room, filled with spider webs and spiders, as a giant one was glaring at them, its legs moving. The two shivered as the cart went up, and all was dark... until the lights came on with ghosts flying and screaming so loud it scared them, as they wet their diapers.

"I don't like this, Charlie! I'm scared!" Itchy cried.

The cart approached the next room as it pushed the doors opened, revealing an upside down room and banshees giggling, along with a ghost emerging from a box, groaning. The two whimpered as they enter the lab room, as the Frankenstein animatronic slowly rose and groaned, holding his hands out. Then they yelled as the cart went down and reached the bottom, arriving the ballroom filled with skeletons dancing, ghosts flying from a pipe organ played by a vampire. They wimpered more, wondering when the ride will end. The cart pushed the doors open, as they end up approaching a graveyard. It was filled with lots of tombstones, and it seemed quiet.

"Guess it seems quiet," Charlie said.

He was wrong. The zombie animatronics shot up from behind the tombstones, groaning. The skeletons jump out rattling. Charlie and Itchy screamed as they hug each other, wetting their diapers more. They yelp when crows flew around them, repeating "Beware! Beware! Beware!" Then the werewolf animatronic emerged from the trees, howling. They screamed and heavily messed their diapers a lot from fright.

The cart finally returned to the starting point, as Charlie and Itchy hugged each other, both in messy diapers and crying a lot.

"Tell me it's all over!" Itchy wailed.

Charlie sobbed as his eyes flutter open, and he looked around. "It-It-Itchy...? It's over," he whimpered.

The two flinched when the power of the ride went out. Then they slowly got off the cart, their diapers sloshing and squelching. They exit the ride and reached their pouches for their spare diapers, but they quickly realized they were empty.

"No more diapers," Itchy said.

"Aw, what rotten luck. Carface only gave us two spare diapers each," Charlie frowned.

Then the two noticed the sun rising, as their night shift was over.

"Well, I guess our night duty is done," Itchy said.

"Yeah," Charlie said. "We sure had fun."

Itchy rubbed his arm. "That I gotta admit, but I just thought of something. Has somebody been here, pulling pranks on us? I mean, with the hoses and snacks with the prunes, and that ride that left us in dirty diapers... it's like someone lives here for a reason as that."

Charlie scratched his head. "Hmm... Could be, but I don't know, Itch. But things can get bumpy in the night when we at least expect it... right?"

Itchy looked at Charlie, but then grinned. "I guess so. I just wondered, that's all." He then yawned. "Come on, Charlie, I wanna get out of this place and have a good night sleep."

Charlie yawned and said, "So do I. You wanna do another night shift in the park again?"

"I think so. There was nothing to be afraid of, except for that haunted house ride that left our diapers dirty."

The two laughed, and they walked as their messy diapers squish and slosh a lot. Pranx emerged from the ride and watched them leave the park, and then he winked a mischievous wink. That rascal sure had fun playing his pranks, didn't he?
