So, have I sold you on that? After all, she can have speed 0ft without having Dex 0.
It seems a bit pointless, since most attackers could kill her by standing just out of reach and chucking rocks.
Hmm... come to think of it, are there any precedents for creatures with 0 move and no attacks at all? The Formian Queen doesn't have any natural weapons, but she's a powerful spellcaster so that doesn't make much difference.
I guess if such a creature existed it wouldn't require a full 3E monster writeup in the first place.
Oh well, I guess it'd be OK giving it a special attack if the lack bothers you.
How about:
An isopterite queen of Colossal size is so swollen and cumbersome she loses the claw attack of her smaller sisters and has a speed of 0 ft. She gains the following special attack:
Flop (Ex): This special attack allows an isopterite queen of Colossal size to crush opponents as a full-round action, using part of her whale-size body to squash them. A flop attack affects as many creatures as can fit within a 30 ft. square area adjacent to the queen's Space.
Flop attacks are only damaging against opponents of Large size or smaller. Affected creatures up to Large size must succeed on a DC Z Reflex save or be pinned, automatically taking ?d?+?? bludgeoning damage during the next round unless the queen moves off them. If the queen chooses to maintain the pin, treat it as a normal grapple attack. Pinned opponents take damage from the flop each round if they don’t escape. The save DC is Constitution-based.
Affected creatures that are Huge or larger are treated as being struck by a Bull Rush attack with a –X penalty to the queen's Strength check (+Y check modifier for a typical Colossal queen).
What do you think?
EDIT: I wasn't
entirely sure about calling this Special Attack "Flop" but it was the most appropriate descriptive word that I could think of. I didn't want to use "Crush" as that's an already defined SA. The best alternative I could think of was "Flounder", but that is more of a random motion.
Also, I did wonder whether the queen can "Flop" with her forequarters as well as her tail end, which implies she could pin opponents under two "Flop areas" at the same time. Although if she could I'd think the queen could only make a flop special attack with one end of her body at a time — although her other end could continue pinning opponents beneath it. :ENDEDIT
