It was a warm day at dragons edge and everyone was swimming in the lagoon when krogan came to make a 'deal'

"What do you want krogan?" Hiccup Asked sternly "well let's start by everyone drinking this and we leave you alone. Do we have a deal?" Krogan said

"O-ok" Hiccup replied nervously and handed out the little vile to everyone. "1...2...3" and they chugged down the drink but then they all blacked out as well as their dragons.

Hiccup woke up to find he was under water but he was breathing. He looked at his legs and saw he had no legs He had fins!

Astrid had a sparkly blue tail and a darker blue shells with a long braid

Hiccup had a green tail with fins going up his arms underneath his arms and his ears were also green. His eyes had no pupil and were all green so no white and he was bare chested

Ruffnut had a brownish-greenish tail with navy blue shells and she still had her three braids

Tuffnut had octopus tentacles and his hair was no longer in dreadlocks
Snotlout had a pale blue tail
And fishlegs had a walrus tail

"What the heck happened?!" Snotlout yelled
"I don't know but first let's find our dragons" Hiccup said but then they saw their dragons but they were not dragons anymore
Toothless was a black eel
Stormfly was a blue&yellow swordfish
Hookfang was an red anglerfish
Barf&belch were two pufferfish but they're fins were attached
And meatlug was a brown turtle

"Toothless?" Hiccup Asked confused "hiccup do you think krogan gave use a potion that turned us into..... what ever we are?"Astrid Asked
"THIS IS SO COOl" "I have tentacles to squeeze the breath out of Ruffnut!" Tuffnut squealed well squeezing Ruffnut who was now purple
"All right, let her go" Hiccup said and separated the twins "let's go above water to see if anyone is there" Hiccup said
He started to swim up and he looked back at the others who were struggling with the tails.
Hiccup sighed and went back to help them

  AFTER THE LESON ON HOW TO SWIM

"Ok gang, are we ready to go?" Hiccup Asked desperately. There was across of yeses and they all started to swim up.

They got to the surface and saw gobber, Stoick, dagur, Heather, and there dragons looking for them

"Hey guys!" Hiccup yelled and waved "HICCUP!" They four yelled and ran to the water "Guys your all ok" Stoick said "how long were you looking for us?" Hiccup Asked dagur "I don't know about an hour!" Dagur yelled "how long can you hold your breath lad?" Gobber Asked "oh! Ummmmmm... well I am going to get out. do NOT freak out please" Hiccup said and dragged himself out of the water
"Hiccup?" "WHERE ARE YOUR LEGS!?" Heather yelled "well I don't know but let me get the gang" Hiccup said and went under water to get them

A few minutes later they all came I over water and swam onto the shore
"Tuffnut?" "You are an octopus?" Stoick said unsure "well duh, I'm not exactly a merman like them." He said with a pouty face

Then a voice talked but there was no one there but them

"Ah hello master Hiccup, seems like you've gotten in a messy situation" and johan walked out of the shadow but there were still some dragon flyers in the bushes with arrows and nets.
Johan did a hand signal and the flyers threw the nets. Everyone swam away to avoid getting caught. Only one person got caught and that was hiccup.

"LET ME OUT!" Hiccup yelled and thrashed around in the net the gang retreated under water and stoick, gobber, dagur and heather all went back to fight the flyers so Hiccup was all alone hanging 10 feet from the water and he was slowly becoming limp

"Ok guys I think the dragon flyers are gone, now we can go look for hiccup." Astrid said
"But I wonder why he did not follow us underwater?" Fishlegs said "I don't know but I don't like it" Astrid said and swam out of the cave and swam to the surface

Once they got there they automatically started to look around for hiccup. Tuffnut felt a drip of water land on his head. He looked up and called out to the others " uh, guys?" "What? We are busy looking for hiccup" Snotlout shot back.
Tuffnut pointed up and everyone saw what he was looking at. "OMG HICCUP!?" Astrid yelled and tried to reach him. He was unconscious in a net all dried up.

Stoick, gobber, dagur and heather came back and saw hiccup in the net and the gang jumping from the water trying to reach him.
Stoick climbed the cliff hiccup was dangling from. "Get ready to catch him gobber." Stoick called out and untied Hiccup and he fell but gobber did catch him.

"Is he okay?!" Astrid yelled from the water.
"I don't know, but he doesn't look like he is breathing!" Stoick said panicked
Johan came and saw hiccup laying on the floor lifeless and sneaked over to a mace and hit The four who were with hiccup and to him with a net but he did not realize the 5 pairs of eyes watching him
