Search the creature.

You have the goblins short sword now, but what else might it have on it? You kneel down and rummage through your conquest's belongings. Small, useless trinkets are the most interesting of it's possessions. You are able to find a bit of cooked meat, but who knows what this thing was eating.. You take the little the creature had. After all it is better safe than sorry. Satisfied that this situation has gone as well as it is going to go for you, you return to camp.
