M’boi tu’is live in the wetlands, nesting among trees and high rock outcroppings. They are huge serpentine creatures with the head of a parrot, and one pair of stubby legs it uses to assist in its slithering movement. M’boi tu’is are watchful of their territories, not only pushing out other rivals to their might but attacking any threats it perceives to the natural world. Although unpredictable and cantankerous, the mboi tu’i often has a casual alliance with other intelligent beings who protect nature, such as fey, druids, and magical beasts.

Territorial. M’boi tu’i are usually submissive toward dragons and other powerful creatures, but do not tolerate the presence of young dragons, behirs, and the like close to their homes.

Omnivorous. M’boi tu’i live primarily on fruits, shrubbery, and vast amounts of swamp grasses, but also snaps up prey animals, and frequently consumes the bodies of its defeated rivals.
