The rabbit blinks coyly and someone takes more damage than a two handed sword! It seems that it would be pretty counterproductive as a lure if the tempting bunny ends up slaying things which are out of reach!
Maybe the ecology of it is that it blasts things to death with its rabbits and then crawls over to the dead prey and eats it?
That's one seriously badass rabbit.
Of course, the concept is that locking eyes with the rabbit suddenly means that you know what it's like to be a plant. You understand the endless tedium, the hunger, the feel of insects boring into your stump. Your meat brain can't process it, though, and if the revelation doesn't kill you outright you stumble towards the bunny as if looking for solace -- at which point the grasping roots grab you, convey you to the chomping maw, and your pain is finally ended.
At least in theory. In practice the WISC gets dazed before it act, gets set on fire, and then rolls two rounds of low-single-digit numbers while you and your buddies go stabbity-stab.
Sniff.
Take a look at those hit points, by the way. 168. The fact that this solo (which I accompanied with the darkswallow swarm to adjust for a 4th lvl 6 person party, making this a straight lvl 4 encounter) lasted only two rounds makes me wonder what the heck grind is like. Doing this again, if I wanted a longer/more challenging fight I'd raise his level and a second bird swarm (I'd also actually remember that the darkswallows have an aura 1. Instead of, say, forgetting it. It didn't have a huge effect on the fight, but it's still galling.) The major flaw with the WISC as written is that the eyestalks and bunnies have an effect on defenses and attack rolls; that's cool in theory but a pain in the butt in practice, because it's minutia the DM has to keep track of on the fly. Better to raise all defenses and attacks one point and remove that feature from the monster.
A revised monster might look like...

Extrude Appendage (Move; at-will)
The Wolf in Sheep's Clothing summons a new appendage: either a new Eyestalk or a new Bunny. The appendage must appear within 3 spaces of the Wolf in Sheep's Clothing.
* The Wolf in Sheep's Clothing begins the encounter with two active Eyestalks and one active bunny, and can never have more than 4 eyestalks and two bunnies.
* Destroying all eyestalks reduces the Wolf in Sheep's Clothing perception and imposes a -1 penalty to hit.
* Destroying all bunnies reduces the Wolf in Sheep's Clothing's defenses by -1.
* The Wolf in Sheep's Clothing can move its Eyestalks and Bunnies anywhere within 3 spaces of the Wolf in Sheep's Clothing as a minor action. This movement may cause opportunity attacks.
* A Bunny is the focus of the Tempting Lure attack -- the attack's range and line of sight is calculated from the Bunny's square.
* Eyestalks and bunnies can be attacked and use the Wolf In Sheep's Clothing's defenses. Any attack that does less than 10 points of damage to the appendage has no effect. An attack that does 10 points of damage or more destroys the appendage and does 5 points of damage to the Wolf in Sheep's Clothing.[/sblock]
