Winx Club Harmonix Dreams Episode 8 part 2

Icy transforms into her Witch form and follows the girls to Frostys Hideout. Stormy, Darcy and Frosty are planning to steal the dragon flame, but instead Bloom erupts in anger and gains her Harmonix. After transforming into her new form, Bloom passes out and turns back to normal. Thinking the dragon flame is theirs, the Trix are ready to destroy the Magic Demention, but the dragon flame escapes from them and returns to Bloom, making her explode like an erupting supervolcano. Stella appears a little while later and saves Bloom, then they go home, leaving the witches plan-less.
