Treant

Treants are strangely related to humans and trees, combining features of both species. ...an individual treant can cause only one or two normal trees to move and attack as stipulated.

Pseudunus and his group looked around, frightened, and realized that three more treents surrounded them, accompanied by a myriad of other creatures. Centaurs, elves, humans, satyrs, halflings, mémechares and brounies surrounded them on all sides, except the one they had come from. Bears and wolves, clearly under the effect of natural magic spells, gritted their teeth and growled menacingly, while snakes hissed in defiance.
