Add a gooball of one of the "normal" types from the toolbar
Select it, and change it's type attribute.
when the list drops down you should see the name of your gooball in the list.
Pick it.

Then Copy and Paste that gooball if you want more than one.

PS. Suggest you use more meaningful / informative topic titles... like..
"How do I add my own gooball in woogle"... rather than just "help me!!!!!!!"

Oh, and remember to restart WooGLE after saving your ball.

i mean which folder do i put it in on the computer to use it on woogle?

You shold put yor GooBall's files into res\balls folder in WoG used by WooGLE

thanks
