Author's Note: Wow you guys absolutely loved the last chapter. Thank you!

Time Period: Race to Edge after the season finale assuming all is well dandy.

Astrid felt weird about this whole thing. The whole reason they took this vacation was to take a break and here they are with a younger version of her boyfriend and his dragon. She sighed as she watched Hiccup try to find some rope to tighten his prosthetic since just his luck it didn't shrink just like his clothes.

"Aha! Found some!" cheered Hiccup as he grabbed some loose rope and tighten his legs so it at least could stay in place. He then examined Toothless' tailfin. "Now, I think all I need to do with your tailfin is just replace the cloth and we can get you back in the air."

"Hiccup," called out Astrid as she caught his attention. "Maybe, you shouldn't fly on Toothless."

"Why not? I'm sure Toothless wouldn't mind the change," asked Hiccup as Toothless roared in agreement as he wanted to still fly on his rider.

"I'm it's not that. We're just not sure if it's a good idea to go flying in your…." started FIshlegs not really sure what's the right word to describe.

"Height?" suggested Tuffnut as him along with Ruffnut and Snotlout snickered.

"Yeah don't you need to be this tall to ride," added Snotlout as he put his hand above Hiccup's above by a couple inches.

Astrid looked at him incredulously as she asked annoyed, "Are you guys seriously still doing those jokes?"

Hiccup nodded as he added annoyed, "I get it. I'm short. I'm small…"

"Don't forget tiny!" suggested Ruffnut happily.

"There's also mini, little, puny," listed Tuffnut as Snotlout kept chuckling.

"Guys! We still don't know what caused this! What if he's gets younger? Do you want to deal with a baby Hiccup?" asked Fishlegs annoyed that they're still making jokes.

"Wait! You really think this could going to get worse!" cried out Hiccup scared that his situation could get worse. He already didn't enjoy being eight any younger, he did not want to be any younger!

Fishlegs was about to deny it but realized he could potentially be right. With no response Hiccup silently freaked out as he tried to keep himself calm. Astrid saw this and walked over to him and kneeled down to his level and said, "Hey, I'm sure it can't any worse. We'll find out what caused this and you'll be back to your normal self."

Hiccup sighed miserably as he replied, "I hope you're right. I don't think I can handle being eight again."

"Not to mention the chance you might have to go through puberty again," added Snotlout as Astrid, Hiccup, and Fishlegs gave him an unamused look. "Just saying."

They walked through the forest as Hiccup rode on Toothless' back. They all looked for a sign as they followed the directions that Hiccup went but still no sign of what might of caused it. Snotlout groaned as he asked, "How do we know if we haven't past it? Hiccup didn't become a kid til this morning yet he stayed as an adult all night til we went to bed."

"I'm sure we won't miss something that turns people younger," argued Fishlegs as he raised a skeptical look towards his friend.

"I'm just saying. What if whatever caused this only affects him when he's sleeping," suggested Snotlout as he crossed his arms.

"Wait, so if we were to sleep right now we would become kids?" asked Tuffnut as he turned to his sister. "Sis! Quick! Knock me out! I want to be a kid!"

Ruffnut smiled as she punched him til Tuffnut fell to the ground unconscious.

Nothing happened though.

"I feel cheated. He's not getting any younger," grumbled Ruffnut as she crossed her arms annoyed that it didn't work, but she did feel pleased that she got to punch her brother.

"Oh gods. I honestly don't think we missed it, cause if we did I'm sure all of us would have been kids. We all past this path yesterday when we went out to explore the island," explained Hiccup though he's still trying to figure out what caused this. Though all this this was making him tired as he let out yawn.

"Wait, are you tired Hiccup?" asked Astrid as she didn't understand why he would be the one tired it was only the early afternoon.

"No!" denied Hiccup quickly as he didn't want to look a like a child as well as being treated as one.

"Hmm, that wouldn't be strange though," said Fishlegs suddenly as everyone turned to him with a curious look. "Well, most children at this age take naps after being awake a certain amount of time add in the fact that he's moving around a lot it's not surprising that his body wants to sleep."

"But I'm still eighteen," argued Hiccup with a questioning look towards his friend.

"Mentally maybe, physically no. Kids tend to tire out much quicker than adults," rationalized Fishlegs.

"I'm not taking a nap," said Hiccup bluntly as he shot his friend a tired yet annoyed look.

"We still need to take a break though," said Astrid as she sat down and leaned against Stormfly.

"Why?"

"Tuff is still out," answered Astrid as she pointed to Ruffnut who poked her brother before she just leaned against Barf and Belch. Other riders leaned against their fellow dragons while she did this as they thought maybe a catnap would do everyone some good.

"Just because I'm eight…. doesn't mean…. I need to… take a nap," said Hiccup before his eyes grew heavy as he felt Toothless yawn as Hiccup leaned against his best friend's head and dozed off.

The Gang all woke up with a start when they heard a scream. They turned to see Hiccup screaming at the top of his lungs as he fell off Toothless. They looked to see what might have frighten him but they turned back at him when he yelled, "DRAGONS!"

Astrid quickly rushed over as she grabbed Hiccup and asked with concern laced in her voice, "Hiccup? What's wrong? Why are you screaming?"

Hiccup took a deep breaths before he shook his head while clutching it as he whispered with slight fear in his voice, "I don't know. I just saw Toothless and didn't recognize him for a moment and just started screaming."

"That's a not a bad thing is it?" asked Tuffnut even though he knew it probably was.

Astrid's eyes widen as she said in shock and fear, "Hiccup, I don't think you're body is the only thing changing."

"What do you mean?" asked Hiccup not liking where this is going.

"I think whatever caused this is making you revert back to your eight year old," said Astrid with fear evident in her voice.

"So that means," started Hiccup as he understood what just happened.

"It means we need to hurry and get you back to your normal self before you completely forget," finished Astrid as even the twins and Snotlout couldn't make a joke as they realized how serious this really was.

A.N: Surprise? Hehe, so yep this is not your average Fountain of Youth story.
