Assassin Vine (4e Creature)
From D&D Wiki
The assassin vine is a semi-mobile plant that collects its own grisly fertilizer by grabbing and crushing animals and depositing the carcasses near its roots. A mature plant consists of a main vine, about 20 feet long. Smaller vines up to 5 feet long branch off from the main vine about every 6 inches. These small vines bear clusters of leaves, and in late summer they produce bunches of small fruits that resemble wild grapes. The fruit is tough and has a hearty but bitter flavor.

 Assassin Vine Tactics
An assassin vine uses simple tactics: It lies still until prey comes within reach, then attacks. It uses its entangle ability both to catch prey and to deter counterattacks. Those that stay out of range are attacked by hurled clusters of Fruit Bombs.
 Assassin Vine Lore
A character knows the following information with a successful Nature check.
DC 15: Assassin vines are semi-intelligent plants with limited mobility, that trap and crush their prey in it's vines to use as fertilizer. The plant produces bunches of small bitter grapes during the summer months. These berries can be used to make a heady potent wine that fetches a high price in most civilized areas.
DC 25 Nature or DC 20 Dungeoneering: A subterranean version of the assassin vine grows near hot springs, volcanic vents, and other sources of thermal energy. These plants have thin, wiry stems and gray leaves shot through with silver, brown, and white veins so that they resemble mineral deposits. The "grapes" of this version are a shiny black. They too are bitter but the wine fermented from them is much more potent then that of it's surface cousin. An assassin vine growing underground usually generates enough offal to support a thriving colony of mushrooms and other fungi, which spring up around the plant and help conceal it.
 Encounter Groups
Few creatures willingly habitate near assassin vines, although some fey or more intelligent plant monsters will use them as traps or for protection of their lairs.
