At some point around 2:20 the front legs do something nice
But I don't understand how the servos are connected to the chassis. The builder was saying in comments that he used 18, so that's either 3 per leg, or some weird combination in the front legs (5?). So, how the heck can the legs rotate like that? What is the servo arrangment?
Anyway. This guy makes a cool sound when walking around (although via R/C)
