Carrion crawlers strongly resemble a cross between a giant green cutworm and a huge cephalopod.
They are usually found only in subterranean areas.
The carrion crawler is, as its name implies, a scavenger, but this does not preclude aggressive attacks upon living creatures,
for that insures a constant supply of corpses upon which to feed or for deposit of eggs.
The head of the monster is well protected, but its body is only AC 7.
A carrion crawler moves quite rapidly on its multiple legs despite its bulk,
and a wall or ceiling is as easily traveled as a floor, for each of the beast's feet are equipped with sharp claws which hold it fast.
The head is equipped with 8 tentacles which flail at prey; each 2' long tentacle exudes a gummy secretion which when fresh,
will paralyze opponents (save vs. Paralyzation or it takes effect).
As there are so many tentacles with which to hit, and thus multiple chances of being paralyzed, these monsters are greatly feared.

Q: How long does (or should) paralysis
caused by a carrion crawler last? And
what, if any, are the effects of multiple
hits by this creature?
A: Paralysis from creautres lasts as long
as paralysis from a wand: 5d4 (5-20)
rounds (DMG page 136). Multiple hits
from a carrion crawler (or any other
paralyzing creature) forces multiple saving
throws on the part of the victim;
when any one is failed, the other hits
have no further effect on the paralysis
(damages still apply if given, such as by
a ghoul or ghast).

Question: How long does the paralysis caused by a carrion crawler, ghast or ghoul last?

Answer: I have always assumed it to be 24 hours.
However, since the duration of the paralysis is not clearly defined in any of the books, I suggest that each DM decide the duration in his particular campaign.
(Correction: The duration of ghoul and ghast paralysis is detailed in REF5. A1 also notes the duration of ghoul paralysis).
 

Question: In TD-37’s “Sage Advice” there was a ques-
tion referring to the paralysis caused by ghouls, ghasts and
carrion crawlers. The reply stated that the duration of the
paralysis was not clearly defined in any of the rule books.
However, a duration for the paralysis inflicted by ghouls is
given on page 15 of T1, The Village of Hommlet. It states that
“Any human or demi-human must save vs. paralyzation or
become immobile for 3-12 turns.” I suppose this is the
official word. Still, what is the duration of the paralysis
caused by ghasts and carrion crawlers?

Answer: According to Lawrence Schick, Vice-President for
Production and Design at TSR Hobbies, the paralyzation caused by
carrion crawlers is of the same duration as that caused by ghouls—
3-12 turns. Paralyzation caused by a ghast takes twice as long—6-24
turns—to wear off.

Q. How long does (or should) paralysis
caused by a carrion crawler last?
What are the effects of multiple hits
by this creature?
A. Paralysis from creatures lasts as long
as paralysis from a wand: 5d4 (5-20)
rounds (DUNGEON MASTERS GUIDE
p. 136.  Multiple hits from a carrion
crawler (or any other paralyzing
creature) forces multiple saving
throws on the part of the victim.
When any one is failed, the other hits
have no further effect on the paralysis
(damages still apply if given, such as
by a ghoul or ghast).

Carrion Crawler--I just needed something nasty for the "clean-up crew, so thought this one up.
 

Great link, Nathal!

So it was Strongheart... I'd forgotten that name.

They don't have the bendy ones that TSR was doing lister, though. the only one of that lot I recall immediately was a poor version of a carrion crawler.
