Blighted Giant

Fungus Infested. The giant counts as being both a giant and a plant in terms of creature types and is affected by any game effect that targets either types.

Poison Spores. Each strike against the giant releases a puff of toxic spores. The first time in a turn when a creature hits the giant with an attack while within 5 ft. of it must make a DC 18 Constitution saving throw, taking 7 (3d6) poison damage on a failed save and half as much on a successful one.

Multiattack. The unclean giant makes two attacks.

Greatclub. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) bludgeoning damage.

Confusion Spores (Recharge 5-6). The unclean giant unleashes a cloud of mind altering spores in a radius of 30 ft. centered on itself. Each non-plant creature in the area must make a DC 18 Wisdom saving throw. On a failed safe, the creature can’t take reactions until the start of its next turn and rolls a d6 to determine what it does during its turn. On a 1 or 2, the creature does nothing. On a 3 or 4 the creature takes no action or bonus action and uses all its movement to move in a randomly determined action. On a 5 or 6, the creature makes a melee attack against a randomly determined creature within its reach or does nothing if it can’t make such an attack.
