I'm sorry you thought I was rude, but I wasn't. And she doesn't use *tools* as in clay carving/sculpting tools (IE these:
[link] ). As far as I can recall, she uses only her fingers to shape everything and her nails for details like the fur texture. So yes, it is entirely possible to make a sculpture without the use of tools. I have done myself a number of times because I make sculptures too.
And yes, I am well aware one's hands can be counted as "tools" if one is inclined to do so. I'm not, so I don't.
