Drop the two scripts in a small, under 10 mass units, object. It will travel in the direction of the x-axis of the object.
A working, editable version of this code can be found at http://slurl.com/secondlife/olivia/17/95/21/ . Look for the small castle.
The code is open and free for you to use as you want. You may use the code in your own commercial products, but may not sell the creature as it stands.
Permission is given to anyone who wants to copy this code to the Wiki.
Put this code in a script called Brain.
