An enormous fungus, a tripod toadstool appears to be a table-shaped mushroom with a trio of trunks and a vine-like tendril on one side. Its trunks are actually legs, while the tendril is a poisonous, whip-like tail. The toadstool feeds on fresh meat by stalking warm-blooded prey and standing upon its victim's remains, its legs absorbing nutrients from the carcass over the course of several hours.
Though its beast-like, fungal appearance suggests that a tripod toadstool is a mindless predator, the fungus is surprisingly intelligent. While unable to speak, the toadstool understands the rudiments of the boggard language, boggards being the humanoids to which it is most frequently exposed.
Boggards occasionally breed, rear, and ride tripod toadstools the way other humanoids breed, rear, and ride horses. A specially-designed saddle can be affixed to the thick, rubbery flesh atop a tripod toadstool's cap through the use of barbed hooks. Attaching a saddle to a tripod toadstool in this manner causes no harm to the fungus. A tripod toadstool mount is loyal to its boggard rider, and is able to understand moderately complex instructions issued in the boggard language.
