A/n: Sorry for the lack of updates! (Excuse time: no wifi + no laptop = no writing)
But I'm back now, with movielover48's idea.
Toothless looked at Hiccup and pouted. He must've prodded the Viking twenty times now, and yet he still wasn't awake.
'Come on!' he hissed in a sharp whisper - it was, admittedly, rather early, and he didn't want to wake anyone else up.
Hiccup moaned quietly, shifted around under the covers for a bit and then flopped back down, still asleep.
Fine. Toothless decided. If he isn't going to wake up, I'll just go without him!
Of course, Toothless wanted Hiccup to be there, so he - rather cleverly, in his opinion - decided to leave a message explaining where he went. He couldn't write Norse, or even Dragonese, so he used his considerable artistic talent to leave a drawing to explain his location. He did it outside, to compensate for how large all his drawings ended up.
Taking the time to nod at his handiwork, Toothless flew off.
Hiccup woke up when a particularly insistent stream of sunlight just wouldn't budge off his face, and he had no choice but to get up and make it move.
He realised how stupid and impossible the idea was about halfway across the room, which was the exact moment that he became awake enough to not be able to go back to sleep again.
Still tired and not quite willing to do any work yet, Hiccup decided to seek out Toothless. It was dawn, which meant that the night fury would probably be on the roof, or some other poor Viking's roof, jumping around to wake up whoever was inside. From the silence from his own ceiling, Hiccup assumed that Toothless was elsewhere, and went outside to go and find him.
It was obvious from the lack of disgruntled villagers at his door, complaining about his dragon, that Toothless wasn't there, either.
Confused now, and slightly concerned, Hiccup looked around the back of his house. Toothless was there, but he had been recently.
"What on Earth is this?" Hiccup wondered aloud, unable to appreciate Toothless's art in quite the same way as the artist himself. The collection of scribbles that Toothless had been quite proud of in no way resembled any location, let alone the one the dragon was actually waiting in.
If he squinted, and turned his head sideways, it almost looked like the indents into the ground were supposed to represent walls, and perhaps the filled in bit was water, not someone's beard.
It was the only lead he had, so Hiccup decided to head towards the cove.
'Aha!' The call from Toothless let Hiccup know that his guess had been correct, before he even managed to poke his head around the entrance. 'I knew you'd get my message!'
Toothless sounded very proud of his art, as usual, so Hiccup decided not to mention that he'd actually not been able to work it out as easily as the night fury was thinking. The dragon's voice was coming from above, and Hiccup looked up just in time to see a blur of black before he felt the Toothless barrel into him.
'Agh!' he shouted intelligently as he flew back, stopping only when the lake decided to get in the way. Sopping wet, and silently thankful that the night fury thought to knock him through the entrance instead of into it, Hiccup struggled into a sitting position. 'Hi bud...'
'Now we can play!' Toothless grinned, bouncing around in the water and splashing more of it on both himself and his Viking friend.
'Yeah,' Hiccup chuckled at the dragon's enthusiasm, no longer bothering to flinch away from the splashes. 'but I'd like to get dried off first!'
Toothless nodded his agreement, crouching down to let Hiccup scramble up onto his back. Once the Viking had found a grip on the now slippery saddle, Toothless took off.
The two flew around for a while, letting the air dry them out. It took a few minutes - and several blasts of warm air, courtesy of Toothless's plasma - to dry off completely, by which point Hiccup had managed to achieve a truly windswept look.
'Let's go back now,' Hiccup decided. 'and try not to land in the lake again!'
Toothless pouted. 'Why not? That's the most fun part!'
'Because,' Hiccup explained patiently, 'we'll end up wet all over again, and then spend the next few minutes drying ourselves off.'
'Okay,' Toothless conceded, 'but we're gonna have to do that at some point today!'
