The right hand enemy gets trapped holding some gold. You can kill him and destroy the gold by digging to the left of the small ladder. You may need to kill the other enemy and trap him in there too.
L' enemic a mà dreta es queda atrapat portant or. Pots matar- lo i destruir l' or cavant a l' esquerra de l' escala petita. Potser necessites matar l' altre enemic i atrapar- lo allí dins també.
