It did appear in S&P, but I also don't remember which issue, but here is the text of it:
Statue of a Shambling Elder God
The statue is of some Elder God, one so ancient that any record of its popular worship no longer exists, a god who is remembered now only in the darkest of cults in their innermost secret circles. Seeing the idol causes a Terror check DC 18. Pausing long enough causes one to 'hear' a mental whisper if the character has at least a 10 Wis. All creatures who hear this horrible whisper within a 60-foot spread must succeed on a DC 13 Will save or be affected strangely for 1d2 rounds. This strange affectation causes the hearer to attack the statue with a melee or ranged weapon on a roll of 1-3 on a d20, or babble incoherently on a roll of 4-10 on a d20, or flee away at top speed on a roll of 11-14 on a d20, or attack the nearest person on a roll of 15-20 on a d20. This is a mind-affecting compulsion effect. A creature that successfully saves cannot be affected by the idol in this manner for 24 hours. Spending any time mediating in front of it or even working around it for a long period of time causes a Corruption save (DC 15). The idol can teach spells, so a sorcerer who mediates in front of the statue after sacrificing a life to it may gain sorcerous knowledge.
