In their first set of challenges, Asterix defeats Asbestos, champion of the Ancient Olympic Games, by beating him in a race, and Cilindric the German in a judo match, by outsmarting his opponent. Obelix defeats Verses the Persian, by managing to throw a javelin further than him. In their next challenge, the pair find themselves crossing a lake that is home to beautiful Sirens, who reside in the centre on the "Isle of Pleasure". Although the Gauls nearly succumb to the women, Obelix comes to his senses when he learns that there are no wild boars for him to hunt and eat, allowing the pair to accomplish the challenge. After surviving the hypnotic gaze of Iris the Egyptian in the fifth task, with Asterix causing him to hypnotise himself, Obelix attempts the sixth task of finishing meals prepared by the Belgian cook Mannekenpix, consuming all the food (which he believes to be his starters).
