Na, I have seen the puppet you were referring too and in hindsight, I had the perfect opportunity to make that happen. Alas, I have already constructed the feet and legs and any alterations would ruin the design. I also used all the fur to make him so can't start over. That style of puppet is definitely on the cards though!
You wouldn't necessarily have to alter it - it could just be a matter of adding something to the soles of the feet, then if it's not to heavy you could hold it up via the mouth mechanism. If a little heavier then add a rod or harness to the waist.
But yeah, without pics it's hard to give some good advice, so if you don't think it'll work then it probably won't.
I suppose it's all okay. It's only art and, art is art, isn't it? Still, on the other hand, water is water. And east is east and west is west, and if you take cranberries and stew them like applesauce, they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
I think we're headed to Mornington Crescent...
