"It was a relief to get out into the greenhouses; they were dealing with more dangerous plants than ever in Herbology but at least they were still allowed to swear loudly if the Venomous Tentacula seized them unexpectedly from behind."
The Venomous Tentacula is a green, spiky, toothsome plant with mobile vines that try to grab living prey. Venomous Tentacula expels venom from its shoots, and its spikes are deadly. Its bite is highly poisonous and can prove fatal.
This dangerous plant is used for student research in Herbology classes at Hogwarts School of Witchcraft and Wizardry. Students are permitted to swear loudly if a Tentacula tries to strangle them during lessons. Diffindo can be used to both stun the creature and sever its arms.
In the PlayStation game, the Venomous Tentaculas live in some parts of the grounds. They spit out spiky ball like pods, that bounce about and can be hit by spells. The Tentacula can also get burned up by the Incendio spell.
