Help/Useful Expressions has some EToys instructions.
The Squeakland images stopped getting upograded when Squeeak went 64-bit (I think).
You can get a "halo" on any object, click the Inspector icon (the eye) and create an etoys script from there.
Also, under Extras/Themes and Colors there is a Set Etoys Mode option. You can try that but, it didn't work last night.
Lastly, files.squeak.org/etoys has a 6.0beta image you can download. Drop the image/changes into SqueakJS [1] (that is the only way to run a 32bit image).
