When an enemy is near, Rudolph's Nose now changes to a constant red color (previously it flashed green-red-green-red) and emits a geiger counter sound.
For the quest "Zap-Eel" (Capture the Zap-Eel in the cage), the player can use any inventory item to block a hole. [Remember to pick up your items after you've nabbed that slippery little bugger !!! :-]
