Well, what a coincidence! There's the nahual in my C1 conversion that you've handily recently downloaded. It's pretty mean, however, as it's designed to run like it did in the original, which translates to a nasty effect with no save on it. Also, check out section 1. The Vault of Chicomoztoc: The Place of Seven Caves, for ideas about statues that come to life under certain conditions. Section 34. Guardians Bar The Way also has an interesting multi-statue trap.
There are more statues that sort-of come to life in Mordenkainen's Fantastic Adventure (WGR5), which was redone for 3e as Castle Maure in Dungeon 112.
If I remember or find any more, I'll get back to you.
