Lousewort was a low-ranking rat in the Rapscallion army who was friends with another rat, Sneezewort. The pair were incredibly stupid, often showing their lack of intelligence. Lousewort was even stupider than Sneezewort, and was often taken advantage of. Lousewort wanted to salvage a ship's wheel from the scuttled Rapscallion fleet, but was ridiculed by Sneezewort and the wheel was thrown away. Unfortunately, it hit the weasel Hogspit, and turned him into an enemy of the rats.
