For the "moving around," you want to right-click on the object and choose
Custom Animation. The effect you want to add is a "Motion Path" effect.
For the walking, you probably saw an "animated GIF" coupled with a custom
animation. The animated GIF probably does the walking in place, and the
custom animation does (with a motion path or a fly-in effect) does the
moving across the screen. Write back if you need more of an explanation
and include what version of PowerPoint you are using (because details of
animations are very different from version to version).
