The story begins with the Snake Men and Skeletor complaining about He-Man. Tung Lashor and Rattlor claim they have a plan to rid them of He-Man, once and for all, and set out to do it. Extendar is visiting the royal palace because Prince Adam wants to introduce him to his parents, King Randor and Queen Marlena. The two Snake Men enter the palace and take the king and queen as hostages. Extendar cannot do anything against it because he does not want to risk their royal lives. Adam runs away and changes into He-Man, who manages to knock them out, but Tung Lashor manages a strike him with his tongue. The poisonous venom spreads and hardens around He-Man until the hero is nothing more than a helpless statue. Extendar tries furiously to crack the shell around He-Man. He finally sets He-Man free
