Bullywugs

Life as a bullywug is nasty, brutish, and wet. These frog-headed amphibious humanoids must stay constantly moist, dwelling in rainy forests, marshes, and damp caves. Always hungry and thoroughly evil, bullywugs overwhelm opponents with superior numbers when they can, but they flee from serious threats to search for easier prey. Bullywugs have green, gray, or mottled yellow skin that shifts through shades of gray, green, and brown, allowing them to blend in with their surroundings. They wear crude armor and wield simple weapons, and can deliver a powerful bite to foes that press too close.
Foul Aristocracy. Bullywugs consider themselves the right and proper rulers of the swamps. They follow an etiquette of sorts when dealing with outsiders and each other, subject to the whims and fancies of their leader — a self-styled lord of the muck. Bullywugs introduce themselves with grand-sounding titles, make great shows of bowing and debasing themselves before their superiors, and endlessly vie to win their superiors’ favor.

Simple concepts in the language are understandable to frogs and toads. Bullywugs use this capability to form strong bonds with giant frogs, which they train as guardians and hunters. Larger specimens are sometimes used as mounts as well. The frogs’ ability to swallow creatures whole provides a bullywug hunting band an easy means of carrying prey back to their villages.
