How the Titans were dethroned

Now that we know that the Titans were the Parents of the Gods, how in the world did their children replace them? I mean, what happened? well as the myth goes, Cronus the most powerful and important of all the Titans (also known as Saturn) and his wife Rhea had children. as she gave birth, Cronus ate ( sort of swallowed actually.. i guess he didn't chew 'em!) his children. He did this because as was foretold one of his children would dethrone him ( same as foretold with his son Zeus, but Hercules didn't take the throne, he just fought his daddy: Zeus). as Rhea gave birth to their last son Zeus, she tricked her husband and gave him a stone wrapped in cloth instead and Zeus managed to survive. in some way, Zeus managed to make Cronus vomit his brothers and sisters( totally forgot how, but I'll make sure I'll remember..sorry!)Then here it came.. the trouble begins.. Zeus told (more like tricked!) his brother Hades to make a monster (or should I say child that looks like a long earthworm with razor sharp teeth sort of like in men in black) made from his own flesh to kill their parents. The name of the Monster?..THE CRACKEN...have you ever watched the movie clash of the Titans? its sort of like that, the one that was supposed to eat princess Andromeda as offering......... Release the Cracken!! (nah! im just joking! hey why isn't anybody laughing?!...try to force it and you will surely fart..trust me.. it works all the time!..okay thats all for now..!!!
