How Do I Make a Ankle Script? Please Answer ASAP, I Tried Many Ways

I Want To Know How to Make a Ankle Break Script w/ a Animation, When Someone Walks Sideways or Spins, the Animation/ Tripping Animation Plays and "OHHHHH" Plays. Then, the Player Who Tripped Lies on the Ground for 5 Seconds.

I Have Tried Making One But It Just Makes the Player Freeze Instead on Tripping and the Animation Playing, Also, the Song Wouldn't Play.
