Piranha plants

Piranha plants
A huge plant like creature springs forth from the pipe before you. In place of its petals is a massive mouth shaped vaguely like an unopened flower. The “head” is dotted with large spikes and the mouth is lined with rows of sharp serrated teeth. The head sits atop a thick trunk that disappeared back into the pipe below.

Piranha plants are huge plant-like creatures with an insatiable appetite for the flesh of the living. They preferred meals are Toadstools and human plumbers, but they are known to eat just about anything. They have spiny heads and rows upon rows of sharp serrated teeth.

Combat
A Piranha plant eats just about anything it senses. Its tactics are simple—lie in wait and attack when food is close.

Improved Grab (Ex)

To use this ability, a Piranha plant must hit an opponent of up to one size smaller with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the foe the following round.

Swallow Whole (Ex)

A Piranha plant can try to swallow a grabbed opponent of up to two sizes smaller by making a successful grapple check. The swallowed creature takes 2d8+7 points of piercing damage per round from the Piranha plants’ tooth lined maw. A swallowed creature can cut its way out by using a light slashing or piercing weapon to deal 25 points of damage to the maw (AC 12). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.

Here's a couple of ideas:

Dex -- (The plant is immobile and shouldn't have any Dex score.)

Also, I think they should have this ability as a supplement to the Improved Grab and a possible alternative to Swallow Whole:

Rend Flesh (Ex):
If a pirahna plant hits with its bite attack, it latches onto the opponent's body and tears the flesh. This attack automatically deals an additional 2d6+9 points of damage.

I agree with the Rend Flesh ability, but keep the Swallow whole bit too. But the one thing that I disagree with is that it has no dex, yes it is immobile but, the plant its self can go back into the pipe and out of it right? So that in turn would give it a little bit of dexterity. Even if its the only thing it can do its a good line of defense and offense.

Hmm... good point.

yeah thats the reason whyI gave it a dex score at all. So it can move in and out of a pipe.

and I like the rend flesh idea as an extra special ability
