He sees how the distance game is played properly now. They may be relying on int 2 and instinct but he has int 10 and explicit comprehension. So long as he attacks only unready opponents, so long as he uses his superior speed to move between them and avoid ambushes, he can reliably kill them without risk of retaliation.

If the herd tried to force him to, defending their dead with zealous rage, he'd have to kill the whole group before he could eat any at all, and most of the meat would rot or be left for scavengers, but they wouldn't bother to force him to do that, would they?

Yeah nevermind that only had one chance of working.

Auroch herds are kinship herds. An Auroch herd that fought losing battles would quickly go extinct. At the sound of a bellow they are scattering every which way.

They cannot stop the dragon killing any of them, but they can stop it killing all of them. Whoever he chases will be the sacrifice that saves the rest.

What does he care he'll pick a victim and flamethrower them to death.

Once he's sure the others are leaving him well enough alone, he'll cook the meat and eat until he is full enough to fly again.

Recently, Nub figured out how to disguise himself as grass by dressing up in gathered foliage. Ever since then, Nub has been passing his stealth checks approximately always.

His preferred hunting strategy is therefore to find smaller creatures, walk up behind them, and kill them in one hit.

Nub is out hunting rabbits when-

You hear the sound of a herd of Aurochs in distress.

It's very loud. It's not very far away.

Nub cannot comfortably take down Aurochs by himself. They move as a herd. If you shoot one, they just circle so that the injured auroch is protected by the others. If they spot you the whole herd stampedes and you are crushed no matter how well you hide, and if they can't spot you they just leave.

What poisons a Goblin Alchemist can make won't take down a beast of their size.

Still, it's a lot of meat, and the horns are quite fetching, and if they're distressed for some other reason maybe there's scavenge to be had.

Nub will stealthily stealth towards where the noise came from, switching his rabbit-gutter for a shortbow and knocking a poisoned arrow.

You come across a Red Dragon Wyrmling eating a dead and burnt Auroch.

He has +10 to Perception.

Nub has a +4 Size bonus to Stealth (Small).
Nub has a +4 Racial bonus to Stealth (Goblin).
Nub has a +5 Dexterity bonus to Stealth (20 Dexterity).
Nub is not wearing any armour.
Nub has a +3 Class Skill bonus to Stealth (Rogue).
Nub has a +2 Skill Ranks bonus to Stealth (He's a level 2 Rogue).
Nub has a +3 bonus to Stealth (Skill Focus feat).
Nub has a +4 bonus to Stealth (Camouflage).
Nub has +25 to stealth.

1d20+10 = 25
1d20+25 = 34

Nub wins.

On paper, there is no way Nub can win this fight.

Nub is level 2 and alone, Dergaix is CR 6.
Even if Nub does any of his favourite sneak attacks, he cannot deal 59 HP worth of damage in the one round it would take the wyrmling to get airborne.
Nub has 2d8 + 0 = 11 hit points.
The DC to dodge the wyrmlings breathe weapon is 15.
Nub would be lucky to survive 18 consecutive seconds of the dragon knowing he existed.

There's no way a small wyrmling can eat a large bovine in one sitting. There will be plenty of leftovers. Nub can just take the rest when it leaves or falls asleep.

Nub should back off to a safer distance, and be patient.

If you tried to sit Nub down and make him do the marshmallow test, he would eat it, stab you, and run off with the rest of the marshmallows before you could finish explaining the rules.

If Nub has a moral philosophy, it is only because he stole it from a seagull.

Nub's not even hungry. He has several rabbits in his bag already.

It's the principle. He shouldn't have to wait around for a dragon to finish eating so he can pilfer the rest.

Nub may be young and inexperienced, but he is still a sentient creature, with a soul and a mind.

Why is this taking so long.

Scholars of goblinology have methodically listed all the plans that goblin-like minds come up with when mere violence seems insufficient.

Nub comes up with #12, the "pretend to be a large group of goblins" plan. This requires making fake goblins out of twigs, tying strings to all of them, and pulling the strings to make them all shake at once.

Nub remembers he doesn't have any fake goblins made out of twigs or the time and patience to set all that up.

Nub comes up with #7, the "provoke one enemy into defeating another" plan. There are many Auroch trails leading away. They couldn't have gone that far. He could make them chase him back here and then they would trample the dragon while he pretends to be a bush.

No that doesn't work the dragon can fly.

Fine, he'll use an expendible item. Nub draws a Smokestick from his bag, and stealthily walks up to within reach of the Auroch.

Suddenly you are surrounded by smoke.

So? He's a dragon. He has 60 feet of blindsight.

Well nobody ever told Nub that.

How far does the smoke go?
10ft, barely enough to conceal the auroch.

Out of an abundance of caution, he'll fly above the smoke. Maybe this is some property of the beast not known to him yet, that it dissolves into smoke some time after death.

Nub cannot actually lift a dead Auroch.
They weigh thousands of pounds. He can't even drag one. Probably an Auroch could drag a dead Auroch, if he tied them together, but it couldn't do it at stampeding speed and that plan obviously ends with a dead Nub.

Nub owns exactly one magic item, a Type I Bag of Holding.
He has no idea what it's standard price is, he didn't buy it at a store.
He's had it for a week now.

Nub barely understood the concept of weight to begin with, and having a magic bag he can put stuff in that never weighs more than he can carry was not helpful to his developing a better understanding.

It's not that the bag has never been full before, but it's always been full of many things. Nub would just empty it out at home and fill it again with new things.

Nub didn't think his bag had a weight limit, or a volume limit. He thought it had a count limit, and only that he did not know what that limit was because he hadn't bothered to count it.

This is the first time Nub has tried to put a single very large object in the bag and for no discernable reason it isn't working.

Also, the body is too big and doesn't fit through the opening.

Dergaix will land directly next to the cloud of smoke, within range of his fire breath.

And he will just sit there and watch.

Fine.
Nub only wants to take the best bits.
Most of it isn't important.

Nub feels around with his hands to the head and cuts off the horns, though it takes him a few moments.

Nub cuts out the eyes, which he thinks an alchemist might value.
Nub cuts out the tongue, which is considered a delicacy.
Nub thinks to try hacking a few slabs of meat off the side.

Should he try to get any organs out of it?

The smoke begins to clear.

Times up?

He'll stand very still and impersonate grass.

For some mysterious reason the dragon maintains direct eye contact, despite his attempts at stealth.

Wait I can explain

Dergaix would like to attempt a Knowledge Local (or possibly Nature?) check to identify the small green humanoid in front of him.
