As a lion drags a dead elephant, the Lord then dragged Kamsa's dead body along the ground in full view of everyone present. O King, all the people in the arena tumultuously cried out, "Oh! Oh!"
Srila Visvanatha Cakravarti explains that many people in the audience thought Kamsa had simply been knocked unconscious when thrown from the lofty dais. Therefore Lord Krishna dragged his corpse so everyone would realize that the evil King was indeed dead. Thus the exclamation ha ha indicates how surprised the people were that the King was suddenly dead and gone.
The audience's astonishment is also mentioned in the Vishnu Purana:
tato haha-kritam sarvam
asit tad-ranga-mandalam
avajnaya hatam drishtva
krishnena mathuresvaram
"Then the entire arena became filled with cries of astonishment as the people saw that the master of Mathura had been contemptuously killed by Krishna."
