"In the mouth of a 20' wide alcove south of the altar basin stands an idol or statue of serpentine stone, expertly sculpted to depict a writhing, amorphous agglomeration of fish, eels, octopi, and other marine monsters. This horrid thing is about eight feet high and nearly as broad, the whole forming a globular mass standing about four feet from the altar basin." - Temple of Elemental Evil
Translating from the original High Gygaxian, serpentine is a semi-translucent green stone. It sort of looks like jade, but is available in much larger quantities. Gygax being Gygax, the inanimate object is going to try to eat you.
