They are chasing you after a bad thing you have done.

Godzilla: GET BACK HERE YOU LITTLE HUMAN!!! COME HERE!!! HURRY UP KONG OR ELSE THEY WILL ESCAPE!!!

Kong: I'M TRYING IM TRYING!!! IM TOO SLOW AND FAT, MY INFINITY GAUNTLET IS HEAVY!!! panting

All you can do is run away from them and keep running as they are big dummies.
