The Fearsome Apes
The path towards the giant tree was a long one and it was filled with all sorts of annoying plants that the party had to be wary of. Not only were the apes constantly attacking them with their seemingly endless numbers, but there were also many plants that would attack as well.
Huge man-eating flowers would suddenly spring alive after someone came close to them and try to devour a person whole, there were other smaller flowers that would produce toxins that they would shoot out in the atmosphere in order to poison and kill anyone nearby. Flesh-eating plants that used vines to attack their prey would launch sneak attacks on the party each time they walked past them.
