In the deep depths of the dark green forest, the dirt path wanders near a great oak tree hovering over a large granite rock.  As our adventurers approach, a figure, clad in green, swings from the trees and lands on the great bolder with skillful dexterity. With a welcoming wave, he bids all, "Welcome to White Deer Forest" and then he explains, with all due manners and great patience, that he will charge each and every traveller 1 gp for traveling through his forest.

Before any weapon can be drawn or spells can be cast, he whistles, and from all the noise heard around, it is clear that he is not alone. He leads a small but desperate, band of men, dwarves, and elves, just trying to survive in the wild.  He also has a mastiff, appropriately named Tiny, as his best friend.

Before anything happens, the dog barks furiously.  The men hide in the thick forest, and all is quite and still.  From around the corner come a kobold and a goblin, weapons in hand, clothes dirty and smelly from being long unkempt.  The goblin has a bandaged arm in a sling, and the kobold carries a great sack that hangs low over its back.  They hurry along the road, but then, they do the unexpected: they hide behind the great rock and rest in the shade of the Oak tree.   The kobold sets the great sack down next to where the goblin rests and starts to gather wood for a fire. In no time, the kobold has a small blaze going and they both are resting and eating some rations.  The longer they rest, the more hitpoints the goblin will recover. When they are finished eating, the goblin will order the kobold to keep watch while he sleeps and recovers. If left uninterrupted for two hours, the goblin will be at full strength.

There are, of course, plenty of men to subdue both the kobold and the goblin, as long as they don't fight amongst themselves.  In which case, both the kobold and the goblin are very likely to escape.  It would be well if the party cooperated and captured the two little enemies and secured the treasure that, unbeknown to all, hides in their plain, white sack.
