Object manipulation is really hard to define. Why? Because they are composed of materials ‘found’ on the street, in your house, etc. This is also why the style is often known as ‘found puppets’.
For example, if you go into your kitchen, you will find all sorts of utensils that make great puppets; a pair of tongs make for wonderful jaws of a crocodile… shopping bags also create wonderfully abstract underwater creatures!

I'm afraid to say that making a muppet-type puppet is far too complicated to explain in one blog comment, however you'll find some excellent starting points there. Additionally, there are some excellent video tutorials that should help you get started (you'll have to scroll down a bit to see their recorded videos):

If you've never made a puppet before, I really recommend you start with something simpler, like a sock puppet. Muppet-type puppets are one of the hardest ones you could make. - But good luck with it either way!
