Special wooden "cross" for BDSM role-play and/or dungeons. It only fits male avatars. Use only the Single 2 ("hands behind the head") pose on the clickable part.
When you merge the .world file, the object will be positioned at around X=0, Y=18, Z=0. There is a huge flashing sphere next to it so you can see it from a distance, which you should of course delete. The object is grouped together.
