The next morning, Hiccup shared her discoveries with the other teens. Everyone, including Snotlout, was eager to find the Isle of Night. They saddled up, and flew in the direction of Bork's last known place of residence: a cave that was located on a small island.
They saw an opening to one of the island's caves and few towards it. Only to find no sign of anything that resembled a cave.
"Well this doesn't add up." said Astro, "The cave was right here. We all saw it. Even you did, Hiccup. There's no way it could've been an illusion."
"I know." replied Hiccup, "But maybe it was Bork's way of keeping himself hidden from dragons. Maybe he had some way of making it look like an illusion. Or maybe he -"
Hiccup was interrupted by a loud yell. Hiccup pressed her hands against her ears, trying to prevent the result of being deaf. She looked at Snotlout, who was trying to make an unrecognisable dragon call.
Fishlegs hovered his dragon next to the Jorgenson boy, "What the hell was that?"
Snotlout smiled, "That, was a Changewing call, my friend. Surprised you didn't know that."
Fishlegs shook his head, "I would've, if it sounded like one. This is a Changewing." Fishlegs inhaled deeply, and shrieked like a banshee.
"Will you keep it down?" asked Astro, as he pointed to the dragon girl, still covering her ears.
Snotlout ignored Astro, "Well then, Fishlegs, if you're so smart, what does a Thunderdrum sound like?"
Fishlegs laughed, "Please." and yelled in a low growl.
Hiccup pulled her hands off her ears as she screamed, "Shut! Up! I can't even hear myself think through the ringing noise you shoved into my ears!"
"Hiccup!" roard Toothless, "I could use my ears myself! Thank you very much!"
Hiccup breathed deeply to calm herself, "Sorry."
Hiccup noticed that everyone was staring at her, with terrified expressions on their faces. Even Astro looked as though he'd seen a supernatural being in front of him.
Tuffnut turned to Ruffnut, "Remind me not to get on Hiccup's bad side."
Hiccup sighed, trying to hide her embarrassed expression in her hands, "I am so sorry, guys. I just..."
"Hiccup. It's fine." said Astro, gently shaking Hiccup by her shoulder, "The bright side is, you got your point across."
Suddenly, there was a loud dragon roar. Practically a Thunderdrum.
"Fishlegs!" yelled Astro.
Fishlegs raised his hands, "That wasn't me! I swear!"
Hiccup pointed to a nearby cliff, "Look out!"
A Thunderdrum flew at the group of Vikings. Everyone flew in the direction of the cave. But the cave was no where to be seen.
Hiccup turned to Snotlout and the twins, "You two find the cave! Me and the others will lure them away! Toothless! Help them find the cave!" Hiccup dismounted from her dragon's back and flew with Astro and Fishlegs to get the Thunderdrum's attention.
The Thunderdrum chased the teenagers all over the place for a few minutes until Snotlout finally found the cave behind a large boulder. But just as he was walking in, the boulder turned out to really be a Changewing grabbed him with its paws and carried him to a nearby cliff.
"Hookfang!" screamed Snotlout, "Help!"
Hookfang shot his fire at the Changewing, but missed Snotlout by inches.
"Go away Hookfang!" yelled Snotlout, "Go away!"
"Jeez!" roared Hookfang, "Make up your mind, Kid!"
Toothless saw the cave entrance, and stared at it as he called, "Hiccup! The cave! Get inside!"
Hiccup followed Toothless' glance and flew to the cave entrance. "Astro! You and Fishlegs lose the Thunderdrum and help Snotlout!"
Hiccup and Toothless flew into the mouth of the cave. The light quickly leaving them as they flew deeper in.
