This slimy grey scavenger lives in swamps and fens, where it fills an important ecological niche by eating everything too disgusting for any other creature to eat. It is approximately 15ft long and 5ft wide, weighing close to 1500 lbs. Although it needs air to breathe, it slides along underwater for long periods while it scrapes its meals off stream bottoms with its mouthful of sharp, inward-pointing teeth. Although it never attacks unless provoked, it does have an extremely dangerous habit. Whenever it needs to breathe, it rises straight up out of the water without bothering to look first to see if there are any boats in the way.
If a giant slug is killed and cut open, there is a 10% chance that its stomach contains a gem, gold item, or 2d6+1 gold coins. All other metals dissolve in the slug's corrosive stomach juices.

Giant freshwater slugs are not normally aggressive creatures, but will attack with its bite if provoked. Although they can sometimes accidentally capsize a small boat, they can attempt to intentionally capsize boats as well. Usually this is done when it is attacked from a boat.

Capsizing Ram (Ex): As a full round action, the giant freshwater slug may ram a boat. If the target boat is smaller than 10ft in length, the captain must make a Profession (sailor) check vs DC 25 (Str based) or the boat is capsized. The DC for a boat between 10ft and 20ft in length is DC 20 (Str based) to avoid capsizing; boats between 30ft and 40ft in length have a DC 15 (Str based) to avoid capsizing.
Boats over 40ft are knocked about, but are not endanger of capsizing. Any characters aboard must make a Balance check vs DC 20 to move or take any action that round.

Hold Breath (Ex): A giant freshwater slug can hold its breath for a number of rounds equal to 10x its Constitution score before it risks drowning. For a typical giant freshwater slug, this equals 150 rounds, or 20 minutes.

Skills: *A giant freshwater slug has a +12 racial bonus to all hide checks when it is underwater.

Vermin Traits: Vermin are mindless - they have no intelligence score and are immune to all mind-affecting effects. They have no sense of morality and are always neutral. They have 60ft. darkvision and any treasure they possess (which is usually none) consists of the property of former victims.
