Blame
Hiccup wasn't happy.
Toothless had gotten into the storage room and pushed all of the food containers off the shelves, meaning that Hiccup took the blame for Toothless.
So after Stoick Hiccup made clean up the mess, Hiccup when to go find Toothless, who had been sleeping on Hiccup's bed the entire time, and scooped him up.
"Toothless do you know what you did?" The cat blinked at his owner and meowed.
"You got me in big trouble" Toothless seemed to be smirking at him.
Hiccup put him down and glared at him "How did you even get in there, it was closed!"
Toothless meowed again and trotted away quickly, leaving Hiccup alone and confused.
"Toothless, where'd you go?"
Meow
He turned around "Toothless?"
CRASH
"Toothless!" Hiccup yelled and ran to where the noise came from, the store room.
He yanked the door open to see Toothless sitting in the middle of the room covered in tomato sauce, the container in was in laid by his side.
….Meow?
"So that's how" Hiccup groaned.
Toothless stared at his owner
"My dad's going to kill me"
Purr.
Toothless got up and walked past him, making a trail of sauce, and went down the hall to Hiccup's room, where he sat on his bed, listening to Stoick shouting and licking himself clean.
A cat has to entertain himself somehow.
