Huey, Dewey and Louie couldn't sleep at all that night. They were too shocked to even try one wink. It was because they couldn't get over what their mom Della told them earlier this afternoon, even though she had to tell them. They couldn't work out whether they were upset that their father was none other than this bad guy Daniel Beakship or that no one, like Della, their uncle Donald or their uncle Scrooge, didn't tell them sooner or maybe it was a mixture of both. Either way, it was too much for them to take them. Not even the optimistic and adventurous Dewey could find any excitement in this. They weren't even hungry to eat or drink anything.

"Come on, guys," said Webby, as she walked into the room and carried her stuff. "Nothing like a good old sleepover to cheer things up."

"Thanks for trying to cheer us up, Webby," Huey said, "but we're just not in mood."

"You've been searching researching this Duck family ever since you could," Dewey said. "Are you sure you knew no more about our father before Daisy and Cy-Rat told you?"

"No, I swear," Webby said.

"Are you sure that our mom, your dad and Uncle Donald didn't tell you before?" Louie asked.

"Well, I did ask them, but they didn't tell me anything," Webby said. "They just randomly changed the subject every time I did."

"Randomly?" Huey asked. "Not intentionally."

"Ohh," was all Webby said.

Then they heard a loud noise.

"Did you hear that?" Huey, Dewey, Louie and Webby asked together.

"That sounded like it came from the hallway," Huey said.

"Let's go and check it out," Dewey said.

They all ran into the hallway and found nothing out of order. No hole in the wall or ceiling, no painting tweaked or collapsed to the floor and no plant pot tipped over or soil even spilled.

The young ducks also noticed that they were the only ones who seemed to have heard them. Scrooge, Della, Launchpad, Beakley, May, June and their new friend Cy-Rat, who was staying the night, didn't seem to hear it. Not even Scrooge's ghost butler Duckworth seemed to have heard it.

"Let's spilt up and search the whole place," Webby said, putting on her night goggles.

The young ducks looked around the whole mansion for clues. They couldn't find anything broken or out of place. They even checked that the rooms of their other relatives and friends and were very quiet about it while they were still in the room.

"Nothing in Launchpad's room?" Huey asked.

"No," Dewey said. "Anything in May and June's room?"

Huey shook his head. "No. Anything in your dad's room, Webby?"

Webby shook her head. "No. Anything in Granny's room, Louie?"

"No. And nothing in Mom's room either."

"What about Cy-Rat's room?" Louie asked.

No one answered which meant no one looked in the room yet so they quietly went in to look in it. The young ducks searched the whole room but they couldn't find anything. They couldn't even find Cy-Rat in her bed or even under it.

"Maybe it was Cy-Rat who made that," Huey whispered.

Then they heard another noise.

"And that one too," Louie whispered. "That sounded like it was coming in the large sitting room."

"Come on," Dewey said.

The young ducks ran back to the mansion's large sitting area. When they got there, they couldn't find anything out of place any more than the last time they checked it.

"I can't even find her in the garden," Huey said, looking out through it.

"Duckworth," Louie called.

Then the ghost of Duckworth appeared. Instead of his usual butler outfit, he was wearing ordinary clothes and a party hat on his head.

"What's the party?" Dewey asked.

"It's a welcoming party, Master Dewey," Duckworth replied. "Every time someone enters the spirit realm, we have to welcome them with a welcoming party."

"Is that why you're not here on night patrol?" Louie asked.

"I don't ever recall him being on night patrol ever," Huey said.

"Master Hubert is correct," Duckworth said. "So, what is so urgent that you had to call me and not your Uncle Scrooge?"

"We just wanted to ask you if you were here if you saw or heard anything," Huey replied. "But now that we know that you didn't, we're sorry we interrupted your –"

"Guys!" Webby cried.

"Shh," her friends whispered.

"You'll give us away," Dewey whispered.

"Oh, sorry," Webby said. "I think I know where our new friend has gone to." Still wearing her night goggles, she was looking under the big chimney. She could see some handprints and footprints had been climbing up it. "Judging by the handprints and footprints, it looks like our new friend Cy-Rat had been climbing up it," Webby reported.

"Well done for finding out the problem yourselves, young sirs, Miss Webbigail," Duckworth said. "Now, if that is all, I must return to the party for the most important bit is coming up. Good luck." With that, the ghost butler vanished back to the spirit world.

"Cy-Rat's deserting us?" Louie cried.

"After she promised us to protect after us from our cruel and evil father and his entire evil sea pirate navy?" Dewey asked.

"Or maybe she used us and do those good deeds to butter us up so she can do something sneaky," Huey said.

"Webby, can you still track down Cy-Rat's handprints and footprints?" Dewey asked.

"Handprints, no. Footprints, yes."

The triplets turned to see Webby standing at the front door.

"You can see the footprints on the ground?" Huey asked.

"I sure can," Webby replied. "And it's leading outside of McDuck Manor and into Duckberg. Come on, let's go!"

"Shh!" the boys cried.

"Sorry again," she said.

"Shouldn't we wake up Mom or Uncle Scrooge or the others?" Huey asked.

Then he saw the others grabbing their gear and heading out.

"I guess not," he said as he closed the door behind him and joined the young ducks heading out of the big mansion gates and into the city of Duckberg.
