Main Lobster (3.5e Monster)

"Awright! Been a long time since we been crawfishin'!"

"Um...these ain't exactly crawdads Abner..."

Main Lobsters are gigantic lobsters that are almost psychotically obsessive about protecting their personal space. Which is a small area of about 60' centered on their current position. Anything entering that area gets attacked suicidally until it dies, no matter how big or small.

Combat
Main Lobsters tend to rush forward and go straight for the claw attack almost mindlessly, regardless of what they are facing. It's amazing their species lives to reproduce.

Improved Grab: If the Main Lobster successfully hits a creature of any size with it's Claw attack it may immediately make a Grapple Check as a Free Action without provoking an Attack of Opportunity. If it is successful it may constrict.

Constrict:  A Main Lobster does 2d8+12 damage with a successful Grapple Check.

Territorial: Once any living being gets within 60' of the Lobster underwater (or within 60' out of the water, and is seen) the Lobster goes into a homicidal fury and attacks, gaining a +2 Racial Bonus on all attack and damage rolls and saving throws for the duration of the encounter.

Blindsense: The Main Lobster can sense all beings within 60' as long as it is underwater.
