It started with a single text.

Short. Blunt. Just spooky enough to raise suspicion.

"Game night. My place. 7 PM. Costumes optional. Spookiness mandatory." —Carrie

Gumball stared at the screen while eating cereal straight from the box. "Is this… an invitation or a threat?"

Darwin leaned over his shoulder. "Could be both. Carrie is half ghost."

Nicole, walking past in her bathrobe, muttered, "If you get possessed, don't call me."

At precisely 7 PM, a creepy fog rolled in—not from the streets, but from the sky itself. The neighborhood dimmed like someone had turned down the sun's brightness settings. A full moon, previously absent, suddenly hovered overhead, glowing a little too enthusiastically.

Carrie's house loomed on the hill like it had been dropped from a haunted movie set. The front gate creaked before anyone touched it. A pumpkin on the porch shifted slightly when Penny passed by and whispered, "Nice costume."

"Thanks?" she said awkwardly.

The crew assembled:

Gumball, in a low-budget superhero outfit made of duct tape and a towel cape.

Darwin, wearing a glowing jellyfish hat he made from string lights and tinfoil.

Penny, glowing naturally and levitating just enough to make the fog swirl around her feet.

Carmen, dressed as a cursed librarian complete with whispering books.

Tobias, decked out in sparkly vampire regalia, looking like Dracula crashed a disco.

Carrie floated at the top of the staircase, arms crossed, cloak billowing though there was no wind inside.

"You came," she said with a half-smile.

"We almost didn't," Gumball muttered. "The trees tried to eat us."

"They're animated for Halloween," Carrie replied. "And slightly carnivorous."

The living room was decorated in full haunted style: cobwebs shimmered across the ceiling, portraits blinked slowly when no one was looking, and the furniture occasionally sighed when sat on. A massive round table stood in the center, covered in a velvet cloth, with strange old board game pieces scattered across it.

Carrie hovered above it dramatically. "Tonight, we play Phantom's Pact—a game older than time, banned in nine dimensions, and rejected by Elmore Mall's clearance bin."

She reached under the table and slammed down a box. The lid was made of bone (plastic, probably) and etched with glowing runes (probably painted on with glow-in-the-dark glue).

A raven perched on a bookshelf cleared its throat. "Ahem. Welcome, mortals. The rules are simple:

Complete a challenge.

Pass the turn.

Fail a task, and… well… you'll see."

The bird coughed out a tiny puff of fire and vanished.

Tobias stood up. "Okay, I'm out. I'm allergic to flaming ravens and spooky monologues."

The door slammed itself shut behind him. Everyone screamed. Except Carrie.

"Sit down," she said calmly.

He sat.

Darwin raised a fin. "Is there… a waiver we should sign?"

Carrie grinned. "Too late."

The game board unfolded itself. Cards flew into position. Dice rattled without being touched. The room dimmed until only candlelight remained.

The first challenge card floated into the air. "Reveal a secret… or unleash a spirit."

Carmen got picked. She sighed, glaring at the table.

"I… I sometimes hide under my own leaves during thunderstorms."

The board glowed green. "TRUTH ACCEPTED."

A ghostly figure emerged from a lamp, gave Carmen a thumbs-up, and dissipated.

"Okay, that wasn't so bad," said Darwin.

They split up. Penny found her reflection flickering between her shell form and spirit form—whispering riddles in reverse. Carmen refused to look in any mirror and just followed the fog. Tobias got stuck in an infinite loop of flexing at himself.

Eventually, Darwin solved the puzzle by slipping through a crack in one of the frames. "Found it!"

The rest dove through, just as the reflections began to step out of the mirrors.

When Gumball's turn came, the room shifted. Shadows swirled like paint in water, and suddenly they stood in a twisting mirror maze. Every mirror reflected not just their images—but different versions of themselves.

One mirror showed a goth version of Gumball. Another showed him in a tuxedo, surrounded by awards. A third… showed him as a snail.

"What's happening?" he asked.

Carrie's voice echoed: "Only one mirror leads out. The others lead… elsewhere."

Back at the table, the game summoned a mini forest in the center of the room. It grew from the floorboards, branches curling toward the ceiling. They were tasked with retrieving a glowing orb from its center—but the trees whispered secrets as they walked by.

"You still sleep with a nightlight," one tree said to Tobias.

"You cheated in gym dodgeball," another hissed at Gumball.

"You sang to your plants," one whispered to Carmen.

"I do not," Carmen snapped.

Back home, Gumball and Darwin stared at the printed photo Carrie had handed them. The shadowy figure was still there.

"Do you think it's… following us?" Darwin whispered.

At that moment, the bedroom lights flickered. The phone buzzed on its own. Gumball slowly turned toward the closet.

"…Bathroom sleepover?" he asked.

"Definitely," Darwin said.

Meanwhile, Carrie pinned the photo into her "Cursed Memories" scrapbook, right next to an old picture labeled "2012: Game Night with the Underworld."

She leaned back in mid-air, watching shadows gather in the corners of her room.

"Same time next week?" she asked the darkness.

It smiled back.
