I am trying to find the character toon geometry that comes with the autorig,
but in my windows search for *bgeo s I couldn't find it, and when I run the tool
the path is $HIP/toon_character.bgeo as a locked node,
any one know in where to find the geo?

thanks .

just export it from the locked version if you want a bgeo file (right-click/save geometry…), by default it's just locked inside of Toon Character Object HDA as you noticed and therefore it doesn't need to reference it from disk so it's very likely that external file is not distributed with Houdini
