Farrowdale mouse
While most experienced travelers are familiar with poisonous serpents and insects, I’d be remiss if I didn’t warn you of some of the unusual venomous creatures in settled lands. For instance, a field mouse that dwells in the forests of Farrowdale sports a pair of curved incisors that continually drip a milky fluid deadly enough to fell a war horse. The mice lair in rotten logs and abandoned gopher holes, eating insects and grubs. Farrowdale mice are whirlwinds of frenzied activity. They dart after blowing leaves, pounce on blades of grass, and snap at any creature who wanders by, regardless of its size.
For the Farrowdale mouse and the copper opossum, use the normal mouse and opossum statistics (award 15 experience points for the Farrowdale mouse, 35 for the copper opossum). If either creature makes a successful attack, the victim is poisoned.
