Sorry, I didn't finish the previous sentence (plus there is a simpler
method, from the Mouth's viewer, in the graphics category is a scripting
tile "mouth | looks like | dot"  drag that onto the world to create script,
the from the Holder's viewer category "collections" drag the "Holder's |
player at cursor" tile on top of the "dot" in the "mouth | looks like | dot"
 scripting tile. The scripting tile will then look like "mouth | looks like
| Holder's player at cursor".  I have been playing with Etoys for a long
time and this is the first time I noticed this method of setting a player's
costume.   Learn something new everyday ;)
