Bat shish kebabs are a delicacy amongst the Dorgeshuun cave goblins. The local goblins make them by first killing giant bats and skewering them on a stick or rod. They heal 200 life points.
Bat shish kebabs can be purchased in the cave goblin capital of Dorgesh-Kaan from one of the many merchants in the marketplace for only 10 coins. They can also be stolen from some of the local cave goblins. This requires level 36 thieving.
