"-and Grunkle Stan is now a young boy." Dipper finished his sentence. He, Mabel, Wendy and Soos were sitting around in the Mystery Shack as Dipper explained to the teenagers what happened the previous day.
"Man, that must've been weird, huh?" Wendy chuckled to lessen the tension she sensed.
"Yeah, it's strange seeing him like this."
"Well, maybe you can use this opportunity to learn more about him?"

Dipper frowned in thought at Wendy's suggestion.
"True, but it's still odd hanging out with Grunkle Stan. Oh, yeah! Soos, did you manage to get the black-light fixed?"
"Yep, dude. It's now working as good as new. Some wires were loose, so I just fastened them back together. So, where is Mr. Pines?" Soos pondered out loud as he handed the black-light to Dipper.
"Thanks, Soos. Maybe I should keep the black-light on me from now on. Grunkle Stan's still asleep. Best not to wake him up yet."

Dipper opened the journal to the page on Youthshrooms and shone the black-light over it. The invisible writing became visible; and it filled the entire page.
"What does it say?" Wendy asked from her chair while Mabel and Soos leaned over Dipper's shoulders.

"'Thanks to my haste, I accidentally picked the smaller Youthshroom; and discovered that it can turn one into a young child. Since it takes five days for the Youthshroom to be completely ingested by the human body, the person that consumed it will gradually turn back into their true age. They will only have the memories and personality of when they were of a certain age, yet they seem to have dreams and nightmares of when they were older. They might not remember much when they turn back to normal, but there's a possibility that they may feel uncomfortable about the idea of someone seeing how they were when they were younger. There's no remedy other than to wait for the five days to pass.'"

Mabel cheered in delight while Wendy, Soos and Dipper glanced at one another in confusion.
"Yah, now we can have lots of fun with Grunkle Stan."
"These five days are going to be so weird."
"Why will they be so weird?" a new voice replied as Stan and Waddles entered the Shack. His question had been answered with silence.

"Good morning, Stan. How did you sleep?" Dipper greeted his young great-uncle.
"Slept okay, I guess." Stan shrugged. It anyone had stared at his face long enough, they would have noticed faint tear-stains on his cheeks.
"Great."
"Morning, Stan!" Mabel waved.
"Mornin', Mabel. So, who are they?" Stan asked as he pointed at Wendy and Soos.
"This is Wendy and Soos; they are Mr. Pines' employees." Dipper replied. Wendy, Soos and Stan simply nodded in response.
"The Shack, what's that?"
"It's a place that has lots of attractions and gifts for tourists that are interested in the supernatural." Wendy explained in a bored tone.
"Really?! That's cool. So, is this our uncle's business?"
"Yep, it's Mr. Pine's pride and joy." Soos proudly explained.

"Cool, so the people that just parked outside are customers?" Stan asked as he pointed at the window. As he was intrigued about the Shack, he didn't notice how panicked Soos, Dipper and Mabel were. Wendy took deep breaths to calm herself down.

Wendy smiled when an idea formed in her head.
"Hey Stan, how good are you at telling stories about supernatural creatures?"
"Very good. Ma even told me I have a great imagination; and even know how to make weird stuff sound possible." Stan beamed with pride as Wendy searched until she found Grunkle Stan's fez and cane behind the counter.
"That's great! Okay, put this fez on your head and carry this cane with you. You are Mr. Mystery Junior, Mr. Pine's great-nephew."
"Wait, you want me to tell them stories about the supernatural? Cool!"
"Not just any creatures, things that are in the Mystery Shack. Can you do it?" Dipper pointed out as he watched Mabel straighten the fez on their young great-uncle's head.

"Of course I can. I will make our uncle proud." Stan smiled from ear to ear.
