"Dangerous-looking thicket of treant-like trees. This is definitely a place travellers should avoid stepping into, though the most imprudent, unfortunately, already have - their skulls hang on the branches protruding from within the thicket, their gold lying deep in the mouth-like cavity, serving as bait for others."
The Treant Thicket is a creature bank in Heroes of Might and Magic V. At this adventure map structure, players can fight treants, hunters, and druids, and be rewarded with gold and wood.
The treant thicket is a good source of wood, which can be great help when building up a town early in the game, but the treants and druids will make sure that ill-prepared heroes pay dearly for it.
