Wheatley Puppet 

Finally my Wheatley puppet is complete! This is a demonstration of him in action. =3 He has 10 quotes in all. This only shows a few. I'm still getting used to puppeting him, so apologies if his movement seems a little weird.
I've got a blog detailing his build process here if anyone's curious: furincosplay.bl...
You can also see some pictures of him here: trp-chan.devian...
FAQ UPDATE:
Thank you so much for all the positive feedback. I'm so happy so many people like my little puppet. I'm having a hard time keeping up with all the comments and questions I've been getting, so I thought I should put up a FAQ list of the questions I keep seeing a lot.
1. How much does the puppet weigh?
Just under six pounds.
2. What are his dimensions?
He's about 12 inches across. I don't have lists of measurements for all his details, but honestly none of them are completely accurate. I eyeballed a lot of things.
3. Can I buy one?
I don't have any plans to start selling these.
4. Can I make one?
Absolutely!
5. Can you tell me how to make one?
I've been responding to some people asking for build advice, but I'm afraid it's starting to get kind of overwhelming. I don't think I can keep giving explanations for everything I'm asked. I do have my blog available detailing the basic process, which should be helpful to anyone trying to make their own core. I know the blog doesn't explain every facet of his design, but I didn't really write it as a tutorial. If you're interested in building your own core, don't feel like you have to duplicate my process exactly. There's really no reason to believe the way I did this is the best way. I had no idea what I was doing when I made my Wheatley. I just found my way through the whole process. In the end it made the project that much more rewarding. If you puzzle your way through some of the steps and come up with your own unique solutions, I think you'll be more satisfied in the end.
