Winx Club (2004)

S01E21 The Frozen Palace

Bloom and her fellow Winx girls are on Sparks, searching for Bloom's dragonfire within the icy palace. Suddenly, a massive yeti-like creature, accompanied by a swarm of fire crabs, attacks the girls and the palace itself. Just then, the Red Fountain boys (excluding Riven) arrive and quickly fend off the fire crabs. The Winx girls then band together to take down the yeti. The episode wraps up with all eight of them aboard the boys' craft, making their way back to Alfea.
