2 days later, they were still sailing back to New Berk as their boat sailed through the open sea.

"Any sign of home yet?" Nuffink asked.

"Not yet, Nuffink." Hiccup said. "We still have quite a long way."

Shortly later, a spouting sound was heard as then they were surrounded by several whales.

"Wow, more whales!" Nuffink said.

They looked and saw the whales as this time they were Gray Whales.

Among the whales, a mother and calf were seen. And they seem to be coming towards them.

Before long, they were directly under them as they appear to be friendlies.

Soon, the calf surfaced right next to them and looks extremely curious.

"Hello, there." Hiccup said.

Hiccup then reached his out and the calf actually allowed him to touch it.

The baby is just 3 weeks old. So they are actually the first humans to ever meet.

The calf soon rolls on it's side as Hiccup rubs his hand across the calf's face, and seems to be enjoying it.

Soon, Zephyr and Nuffink were able to join in as the calf looked like it was really enjoying itself.

"It's so smooth." Zephyr said.

Soon, the calf was playing along as it manages to push the boat a bit with a nudge. And even twist and rolls at the surface as it was almost like an overgrown puppy. Soon Astrid was able to touch the baby as Hiccup has manage to get his inside the calf's mouth, fortunately for him there was no teeth as it was only bristles of baleen. But the calf really seemed to enjoy having having the inside of it's mouth rubbed.

"I think it likes it's mouth being rubbed." Zephyr giggled.

"I think it does." Hiccup said and laughed a bit.

Soon, the calf's mother joins next to them as she was twice the length of their boat. And her head was covered in patches of barnacles. Even she allowed them to stroke her, but were careful not to cut their hands from the barnacles.

The mother and calf stay close for nearly an hour.

Eventually, the Gray Whales begin to move on as well as the boat.

A few hours later, their boat continues sailing as a nearby rocky outcrop was seen with a group of birds were seen.

"Hey." Zephyr said. "What kind of birds are those?"

"I'm not sure." Hiccup said and looks through his spyglass.

He looks at the birds, and saw they were black with a white underside with a white spot near their eyes.

They were actually Great Auks.

"Oh, it's one of those seabirds we used to see every once in a while back on Old Berk." Hiccup said.

They soon pass by the rocks when then suddenly, the boat felt like it bumped against something.

"What was that?" Astrid said.

"I'm not sure." Hiccup said looking over the boat. "I don't see anything under us."

Then water was heard breaching as they looked ahead of the boat and saw a disturbance on the water surface ahead of them.

"Uh... what is that?" Nuffink asked.

"I don't know." Hiccup said.

Then a faint sound was heard as a small glow was seen in the water, and then part of the water started to collapsed as the family of 4 took a step back.

Then suddenly a large tall jagged-shaped object rose from the water along with several more as they were dorsal plates. And then they rose up as they flashed blue as then a charcoal color body rose up as then a pair of large wings appeared, and then the creature growled as it then rose up as water poured down as they watched.

The creature continued rising higher as then it was revealed to a colossal Wyvern dragon bigger than a Bewilderbeast. 400 feet tall, and has a pair of horns on it's head.

The dragon continued rising as he stood to his full height as then a pulsating hum was heard as it grew louder and his wings were spread out. And then his chest showed a blue glow as his eyes flashed blue, and then he lifts his head up and fires a powerful blue blast as he roars out as the blast went high in the sky.

Then a bright flashed occurred in the sky as the family of 4 watched.

The dragon soon ceased his blast and lowered his head down. But then he noticed the boat below him as they got nervous, the dragon then lowers down and nears them as he snorted a large gust of wind from his nostrils.

"No one move." Hiccup said.

The dragon stares down at them with a firm look, but after a few moments his expression seems to lower with a gentle look.

Soon, the dragon lifts his head up and then turns and then brought his wings out and then takes off into the air as his massive tail was lifted up. And then crashed into the water again creating a large splash as the family of 4 held on and watched him as he flies off into the distance.

"What was that?" Zephyr asked.

"I'm not sure." Hiccup said.

A week later, they were back home on New Berk and they decided to spend a day by the lake where Hiccup followed Toothless to where he was with Luna.

As soon as they got to the ledge leading to the lake, they suddenly saw something that was a shock for them.

On the beach below them, was an actual dragon.

It was an unknown species of Fury dragon. It looked a lot like Toothless, but with huge differences. It was all blue, only 2 ear flaps, no dorsal plates, about the same size and similar tail fins like Toothless.

"Whoa." Hiccup said softly.

"Is that a Night Fury?" Nuffink whispered.

"No, not really." Hiccup said. "It seems more like a, uh..."

"A Blue Fury." Zephyr said.

"Yeah, I guess it's more suitable." Hiccup said.

They watched as the Blue Fury lays on the sand as it hasn't noticed them yet.

Then suddenly a loud honking bellowing sound was heard from a distance as everything went silent.

The Blue Fury was also alerted by it as it listened, and then it flies off.

"What... was that?" Zephyr asked.

"I'm not sure." Hiccup said.

Later towards night, after tucking the kids into bed, Hiccup was finishing cleaning a few dishes from dinner. For most of the day, everything has been relatively quiet since the loud sound was heard.

Soon, he through one of his old journals in the days of the Edge, and through the drawings of the 4 creatures that he and Astrid were shown after their encounter with Kong. Truth be told, he wasn't exactly if they truly existed. But there was something about the drawing of the giant lizard creature fighting the 3-headed dragon that he couldn't stop thinking about.

He then turns the page to a drawing the lizard creature, and then slightly wondered if the loud sound was actually a roar.

"Oh, buzzkill." Hiccup muttered.

"Buzzkill." Said a little voice.

Baffled, Hiccup then turns and saw Zephyr sitting at the base of the staircase.

Hiccup then made a gesture for her to be quiet knowing that Astrid would probably kill him if she caught her awake and out of her bed.

"What do you think you're doing up, little miss?" Hiccup whispered.

"Buzzkill." Zephyr said.

"Nope. We don't say that." Hiccup said. "Only Mommy says that word. She coined it. It belongs to her."

"Why are you up?" Zephyr asked.

"'Cause I got some important buzzkill going on here!" Hiccup said. "Why do you think?"

Zephyr then gave a look to him something similar he used to make when younger.

"No, I got-I got something on my mind." Hiccup said. "I got something on my mind."

"Was it Toothless?" Zephyr asked.

Hiccup thought for a moment. "Sure was." He said. "That's extortion. That's a word." He got up. "Great minds think alike." He then lifts her up. "Toothless exactly on was on..." He heads up upstairs and glanced over to the tapestry of Toothless. "...my mind."

Hiccup soon brought Zephyr back to her and Nuffink's room as he finishes tucking her in.

"You good?" Hiccup asked as Zephyr nodded. "Yeah? Now you are." He then hands her a stuff Night Fury that she was given on her 4th birthday.

"Tell me a story." Zephyr said.

"A story." Hiccup said. "Uh. Once upon a time, Zephy went to bed. The end."

"That is a horrible story." Zephyr retorted.

"Come on, that's your favorite story." Hiccup said. "Love you tons." He leans in and kissed his daughter's forehead.

"I love you 3,000." Zephyr said.

"Wow." Hiccup smiled.

He then got up and blew out a candle.

"Wow. 3,000. That's crazy." Hiccup said and got to the doorway. "Go to bed or I'll sell all your toys." He tried to be stern in a funny way and closed the door. "Night night."

Zephyr silently giggled.

Shortly later, Hiccup met up with Astrid in the living room.

"Not that it's a competition or anything... but she loves me 3,000." Hiccup said.

"Oh, does she, now?" Astrid said sounding offended.

"Oh, Astrid, come on, it's nothing like that." Hiccup said. "I'm sure you're something in the... 9 to 1200 range. Besides, I'm better sure Nuffink has something similar for you."

Astrid couldn't help but laughed a bit. "She is clearly like you sometimes."

"Yeah, well, I think she's sometimes almost like you." Hiccup joked.

"Okay, sometimes I wonder if she's more stubborn than the both of us combined." Astrid teased.

Hiccup then gasped in fake horror. "Oh! We're going down that way, are you?" He playfully nudged.

Astrid then laughed a bit. "You asked are it. If memory serves me, I recalled it was your idea to start a family."

"Oh, how dare you!" Hiccup said and grappled her as she laughed. "That is a low blow." Astrid then tries to get away. "No, no, not this time."

But then Astrid slipped from his grip and then twisted his left arm.

"OW! Okay, okay!" Hiccup said quickly giving out. "You win!"

"You're still so predictable." Astrid laughed a bit resting her chin on his shoulder.

"Uh-huh. Right." Hiccup said and laughed a bit.

He turns to the tapestry of Toothless.

"You okay?" Astrid asked.

"Yeah, I'm fine." Hiccup said. "Just... thinking about Toothless."

Astrid then wrapped her arms around him.

"I really miss him." Hiccup said.

"You know, I do too." Astrid said. "Just as much as I miss Stormfly."

Hiccup sighed. "I'd give anything to let him live with us again."

"I know." Astrid said. "But at least he's in a safe place. Along with all our dragons."

Meanwhile, hundreds of miles away in the sanctuary of the Hidden World, Dart finishes a small drawing of Hiccup along with Astrid, Zephyr and Nuffink.

She then placed the stick in her mouth down as then Blue Night appeared as they stared at the drawing for a few moments.

Then Toothless appeared and saw the draw Dart them, he then crooned as he nuzzled her.

Toothless then flies off as Dart and Blue Night followed them, and they soon rejoined with the pride as Alpha and Asmund have recently came back from a fishing trip. They soon dropped big mouthfuls of herring and a few salmon as Dart, Blue Night, Pouncer and Ruffrunner started feeding. And soon, Blue Night's 2 brothers, Flash and Talon, and Blue Night's albino sister named Frosty.

As the 7 cubs were feeding, Toothless lightly warbled missing Hiccup. Luna went up to him, and nuzzled him in comfort.

Then suddenly, Bolt was seen flying up in high speed as they turn to him. Then Ink appeared from the opposite direction as they turn to her.

They then turned back to Bolt as the 2 looked they were coming at each other.

They watched as the 2 gained speed as they both split open their dorsal plates, then right as they were about to hit each other, they quickly peeled right narrowly avoiding each other by a few feet.

Bolt then roars in triumph as he spun in the air.

Toothless merely shook of the 2 stunt devils as well as Alpha of his 2 younger siblings.

Author's Note:

Now I know what you're thinking.

Gray Whales in Atlantic waters were they're a Pacific whale. Well, they were actually common in the Atlantic during Viking times. Until eventually the Atlantic population was hunted to extinction.

As well as Great Auks before they too vanished to extinction.

And soon, you'll learn more about this new giant dragon.

And yes, there's an Avengers: Endgame reference with Hiccup and Zephyr. Since Zephyr has a personality like Hiccup's, I assumed they were close.
