So the creature wanted a bribe in order to leave them alone, a concept Robin was familiair with. He also had no problem with it as long as he didn't have to pay and there was a guarantee it would keep it's deal of the bargain.

She had even proven to have some experience with bribes as she tried to get some extra advantages for her money or food in this case. Still he kept his bow drawn but aimed it at the ground, in case the creature didn't keep it's side of the bargain.
