Bon et bien j´ai trouvé mon compte sur un autre forum et je vais copier/coller la façon de les battre pour ceux qui un jour seront pris comme moi (désolé c´est en anglais, sortez vos dictionnaires :P )
To defeat the two skorpions, the twin blunder tails; its just about impossible to win fighting both of them at once. So fight one at a time. When the challenge starts, you are facing the twins in the arena. There are four bridges. Three small and one large. The large one is at Spyro´s back. Head straight for the bridge to the left of Spyro. The Blunder Tails can´t get you here. One will face you while the other tries to circle around you and falls into the water (mote). Now you are down to one. That´s half the battle!!! Now there is two ways to defeat the last skorpion. 1.) Headbutt him on the bridge until he flips onto kis back and do the tail bash a.s.a.p. or he´ll get back up and his life will return by half. 2.) Go out into the arena but be forwarned he fights from a distance and will not stay close. Charge up to Blunder Tail head to head. Use your horn knock-up (the O button, hold) then use your tail strike (XXO hold)as soon as he is on his back. Now you did it buy spyro can´t take the fame and passes out (goes catatonic) again to go meet the chronicler.
