False Appearance. If the violet fungus is motionless at the start of combat, it has advantage on its initiative roll. Moreover, if a creature hasn’t observed the violet fungus move or act, that creature must succeed on a DC 18 Intelligence (Investigation) check to discern that the violet fungus is animate.

Multiattack. The fungus makes four Rotting Touch attacks.

Rotting Touch. Melee Weapon Attack: +7 to hit, reach 20 ft., one creature. Hit: 13 (3d8) necrotic damage. If the target is Medium or smaller, it is grappled (escape DC 10). Until this grapple ends, the violet fungus can automatically hit the target with its Rotting Touch attacks, and the violet fungus can't use one of its Rotting Touch attacks against other targets.
