Shellder (3.5e Monster)

Shellders are usually teases. They enjoy showing just enough of themselves and waggling their tongues enough to attract attention, and then clamping shut. Shellders resemble clams, and are rumored to be quite tasty. Shellders are hairless, and can close very tightly.

If anything gets inside their crack, they reflexively squeeze it much harder than a creature their size would seem to be capable of. Shellders are known to like the taste of tail, and frequently lick, bite, or grasp the end of the Slowpokes.

Shellders have long and useful tongues, which they can tie knots with.

Combat
Shellders do not treat combat seriously, and usually insult or flirt with their opponents. They usually like to clam up, thus denying those around them access, in order to increase frustration.

 (Ex): A Shellder can pull itself closed very tightly. If a Shellder fights defensively, it also gains three quarters cover (+7 AC, +3 to reflex saves). If a Shellder goes full defensive it also gains nine tenths cover (+10 to AC, +4 to reflex saves, and improved evasion). A withdrawn Shellder does not provoke attacks of opportunity.

 (Ex): For the purpose of grappling rolls, a Shellder counts as two sizes larger and effectively has a +20 bonus to strength. This usually translates to a +18 grapple bonus.
