From the preview:
Dwelling amongst the huge trees of the Chaq-Itza rainforests, the Jungle Trolls are a species of troll that have adapted perfectly to their arboreal habitat. Their arms are longer than those of their northern cousins’, ending in curved claws which they use to clamber amongst the treetops. Although they are herbivorous, eating the leaves and fruit of the trees they live in, they are highly aggressive when provoked, especially if they are protecting their young. The claws which they use to climb are just as effective at tearing apart flesh, and as such a maddened Jungle Troll is yet another peril of the Chaq-Itza that one must try to avoid at all costs.
Young trolls are often captured by the Jungle Gremlins, and raised as beasts of war—their huge bulk smashing apart enemy lines. Their herbivorous nature also means that their victims are left uneaten and tenderised, much to the glee of the hungry Gremlins!
