While having a picnic in the local park, Twilight stumbles upon an oddly placed rock with words etched into it "Who ever finds this chest must understand the powers it posses are joined with the chosen ones". Twilight uncovers the chest and finds six coloured jewels inside, she shows them to her friends where Rarity begs to have them. This goes down as you'd expect. When they touch the gemstones they activate something magical within that has spread to them. Now the six friends must learn to harness their new found powers to fight a rising evil.

Mlp and Winx Club crossover, if you are wondering what transformation they have its going to be the first one magic winx.
