The infamous roaming ivy of Latius Woods. These monsters are thought to originate from the native ivy, which may absorb magic as it invasively spreads throughout an area. Just as plants will stretch out new tendrils to reach sunlight, it is thought that this monstrous ivy also began moving to absorb energy from the sun. But the Latius Woods are wrapped in such constant shadow that it would seem that this specimen took the expedient route of becoming carnivorous instead so that it might absorb energy from its prey.

Since an ivy looks like a normal plant when at rest, a DC 20 Perception check is required to notice it before it attacks for the first time. Anyone with ranks in Survival or Knowledge (nature) can use either of those skills instead of Perception to notice the plant.
The master of an ivy familiar gains a +3 bonus on stealth checks.
