Surfacing from the depths emerges a colossal slug. Its swollen flesh is a hideous mottled greenish-gray and rows of undulating gills line its 30- foot long body. Probing with a large set of antennae it gnashes its great mouth exposing a gullet lined with rows and rows of serrated teeth.

A giant sea slug can attempt to capsize a boat or ship by ramming it as a charge attack and making a CMB check. The DC of this check is 25, or the result of the captain's Profession (sailor) check, whichever is higher. For each size category the ship is larger than the sea slug's size, the sea slug takes a cumulative -10 penalty on this CMB check.
