Find OOX-09/HL!

You have uncovered some sort of strange, egg-shaped device made from metal. Fiddling with one of its knobs springs the egg to life, as it opens up into some sort of gnomish robotic contraption! A voice from inside the robotic egg crackles to life. "My name's Oglethorpe Obnoticus, and my homing robot has crashed! I will reward you for its recovery; please take this beacon to the robot!" "I now have computed the coordinates of the robot for you; it crashed at the head of the river near Skulk Rock!"
