How to create a running animation sprite?

Question

Animation

Hello. I am creating my own simple game. The main character is a puppet. Graphics decided to create a pixel. The animation of "doing nothing" turned out with a bang (I just removed 1 pixel from the bottom of the character), but the running animation does not work at all. I looked at many examples on the Internet, but I did not achieve the desired result. Help me please.
