Margoyles either remain still, then suddenly attack, or dive into their prey.
Freeze (Ex): A margoyle can hold itself so still it appears to be a statue. An observer must succeed at a Spot check (DC 20) to notice the margoyle is really alive.
*Margoyles receive a +8 racial bonus to Hide checks when concealed against a background of unworked stone (such as is found in caverns and caves).
The Margoyle first appeared in S4 The Lost Caverns of Tsjocanth (Gary Gygax, 1982). It was called the Marlgoyle in S4. Note the extra "l".
