Will somebody help me control this new Rig my friend sent me?

So basically, if you’ve ever seen the minecraft parody song called “Revenge”, My friend made a blender rig of it, and i would like to know how i would go on putting it into an animation! I would also like to know how to change the poses and stuff! So i would like to know how i would change poses and stoff plz :3

There are several ways of animating characters, props, etc. You need to get familiar with Inverse Kinematics, Forward Kinematics, target bones about the rig along with Shape Keys. But before all this stuff, get into basics of animation in particular with

  1. Time and Space
  2. Anticipation
  3. Weights
  4. Follow-through
  5. Different Walk Cycle

…and remember animating anything either in 2D or 3D is most time consuming and tiresome job in the entire workflow, but also loads of fun and gratifying at the same time, when you see your results come ‘alive’.
