Is based in this image: [Quadruped Box](http://lolworthy.com/wp-content/uploads/2015/10/is-halloween-getting-too-sexy-for-kids.jpg "Quadruped Box")
Is very rare, I know! :O. Is very compatible with chairs!!!
Left legs: 7 Numpad
Right legs: 9 Numpad
Left legs: 1 Numpad
Right legs: 3 Numpad
If you need turn left, you must move the right legs, and if you need turn right, you must move the left legs.
Notes: The Quadruped box is very crazy for walk, but is not a big problem. I hope you have control of this dupe made by me :-)
