Monster I'd Like to Fight: Boot Bugs

Parasitic Bug Masquerading As Footwear

Habitat: Forest, Grassland, Underdark; Treasure: None

Boot bugs are foot-sized, leathery creatures resembling caterpillars. Their most striking feature is a large, expandable mouth on their abdomen, which they use to envelop and attach to the limbs of their prey. Once secured, the boot bug moves in tandem with its host, feeding on them with its tiny teeth.

These parasites strike when their prey is resting, often replacing a creature’s actual boots without notice. If discovered while attached, a boot bug will deliver a swift, painful bite before fleeing. Removing one quickly but carefully reduces the risk of injury.

Despite their parasitic nature, boot bugs have been used medicinally to treat conditions like fighter’s foot and toe jelly, much like leeches in traditional medicine. For instance, one week of consistent boot bug use will completely resolve inflamed fighter’s foot, with skin returning to its normal appearance a few days later.

To avoid detection, a boot bug adjusts the texture and pressure of its form to mimic comfortable footwear. Roll once on or choose a result from the Boot Bug Comfort table to inspire the sensation it creates.

Boot Bug Parasitism


A boot bug secretes numbing saliva, allowing it to feed unnoticed throughout the day. Over time, this slow nutrient drain leaves the host feeling unusually hungry and fatigued, requiring extra food to stay energized and induces unusual cravings. Roll once on or choose a result from the Boot Bug Cravings table to inspire the food the host is yearning for.
