An Emergency Guide III

This is just a random idea that occurred to me this afternoon. I was like "wow, think if Hiccup would leave Berk for a couple of days and Toothless had to stay... would he cause trouble or not? Would he be docile or a headache? ... etc, etc..."
Call it a potential fic. I figured, being that there's a growing bond between Hiccup and Stoic, I guessed they'd take trips to haunt and stuff... but I don't think Toothless would always go with them. After all, it IS competition to Stoic.
Then I thought, Toothless isn't always nice with everyone, especially the ones who've treated Hiccup badly.
It was then when I realized Hiccup being the smart cookie he is, would've done a guide on how to at least appease Toothless while he's gone.
I know, I know... it's a silly and unproductive idea but I had fun doing it
Do you think the guide would work? Feel free to add rules on the comments section or how you think Toothless would act if any of the Vikings were to try to follow or break these rules
