Are there any stats for skunks, dire or other, in 3.5? I have so far been unable to find them if they exist, so I decided to turn to the people who would know best.
3.5E stats for the skunk can be found in the Tome of Horrors Revised by Necromancer Games. That book also has the Dire Template, which can be added to any animal to get the dire version of that animal. They also published a free supplement, consisting of all the animals from the ToH Revised with the Dire Template applied, including the skunk. You can find that free supplement here.
