The morning sun was shining brightly over the island of Berk. Hiccup Horrendous Haddock III was getting out of bed. He had plans to make saddles and hang out with his friends today.

He had finished eating his breakfast, but his dragon, Toothless, barely touched his food. He had a high fever and his stomach had an uncomfortable feeling inside, which made him not want to eat any food.

"You okay, bud?" Hiccup asked Toothless with concern. "You haven't touched your breakfast."

Then Toothless coughed loudly like ill people would do. Shortly after, he sneezed which made plasma blasts come out of his mouth.

Hiccup backed up in shock and fear as the plasma almost struck him. Now he was more concerned than before about Toothless.

While in the ring arena with his friends, Hiccup was talking with them. Toothless sneezed again. He had been sneezing, coughing and puking most of the day.

"Is your dragon alright?" Fishlegs asked.

"I don't think so." Hiccup replied. "I think he's sick."

"Maybe you should talk to your father about it," Astrid said.

"Maybe you're right." Hiccup said.

A while later, Hiccup was leaving the arena. Toothless sneezed behind him. Hiccup jumped at the sound of the sneeze and didn't get hit by the plasma.

Then his father, Stoick the Vast, the chief of Berk, stepped up.

"Oh, dad, thank goodness you're here." Hiccup said.

"I heard Toothless sneeze. I hope you're alright." Stoick said with relief.

"I'm okay, but I'm concerned about Toothless. He's been sneezing, coughing and puking all day. He didn't even eat his breakfast. I think he's sick."

"I believe you're right, son." Stoick said sympathetically. "There's a Viking who has the ability to heal sick and injured dragons. He lives on an island a short distance away from here. I'm gonna take you and Toothless to him. Come on." Hiccup and Toothless followed him to a ship.

Once they were all on the ship, Stoick began to steer the ship towards the island he mentioned. Toothless is still sneezing, coughing and puking. He had to sneeze and puke towards the sea so he doesn't cause any damages to the ship.

An hour and a half later, the ship arrived at its destination.

"Well, here we are." Stoick announced. He, Hiccup and Toothless got off the ship and walked on the island.

In front of them, stood a hut made of bricks. Stoick walked up to the door and knocked on it. A man with brown hair and a brown mustache opened the door.

"Ah, Stoick the Vast! Long time no see! How you been doing?"

"I'm doing good, William. How about you?"

"I'm doing good myself. I've been taking care of myself and hanging out whenever I don't have any dragons to heal."

"This is my son, Hiccup. Hiccup, this is William. He's a dragon healer."

"Hi," Hiccup said.

"Nice to meet you, Hiccup." William replied. "So, what can I do for you two?"

"My dragon, Toothless, is sick." Hiccup answered. "He's been puking, coughing and sneezing all day long, and he can't eat because of a stomachache. Can you heal him?"

"Sure I can." William said. "Let me have him."

Toothless backed up unprepared for what William might do to him.

"It's okay, bud. He's going to help you get better." Hiccup assured his companion. With that said, Toothless walked over to William. As soon as he did, he puked and coughed and sneezed afterward. He made sure not to do any of that in William's direction.

"How long will it take for him to get healed?" Hiccup asked William.

"Well, depending on how long it takes for me to heal him, it'll probably take... two or three days."

Hiccup walked up to Toothless and looked him in the eye as he said, "Good luck, bud. I hope you get well soon." He gives him a hug and lets go.

"Well, thank you, William. We should be on our way now." Stoick said. "Come on, Hiccup."

Hiccup started to follow his father. He looked back at Toothless sadly and headed back to the ship with his father.
