Hey guys, I would like to ask if anyone know how to make paper toys walk like this? What is the mechanism behind this? I suspect a pendulum or something similar

It is most likely a rubber band mechanism similar to the one here.

I don't see a pattern offhand, but I'm pretty sure that's the general idea.

What an amazing blog! Thanks for the link

Here's an article on wooden ones that work by the same principles http://makezine.com/2015/08/10/wobblebots/
Exactly. And here is a 3D model on Thingiverse for a very similar robot.
The principle is two independently moving legs which rotate around a horizontal axis in a small angle range (about 30°). When the center of gravity of the whole figure plus of each leg is correct, as well as the angle of the slope, then you get the kind of movement you see in your link.
The principle is not difficult, but creating the parts in paper so that they have the correct center of gravity, low friction for the rotational movement of the legs and high enough friction between the "soles" and the floor is tricky.
In any case, you don't need a pendulum, as the whole figure is the pendulum, and you don't need any wind-up mechanism.
I will definitely look into it, thank you kind stranger
