The Big Flower Fight

The dome is abuzz with bees, beetles and butterflies as the contestants craft giant bug sculptures out of flowers and plants for the first challenge.

The teams take on an assignment combining floristry with fashion, working with thousands of cut flowers to create couture gowns for human models.

Lions and lemurs and hares! There's not a petal in sight as the artists assemble fantastical furry creatures out of grasses and recycled materials.

The teams have a tasty new task to tackle: forging enormous thrones made of fruits, vegetables and other edible delights.

Fireworks burst, cyclones swirl, and pigs fly when the contestants use colorful dried flowers to form floating sculptures suspended in midair.

Vying for a spot in the semifinals, the teams build their biggest sculptures yet: whimsical sea creatures made from coastal plants and beach waste.

The contestants get their hands dirty in their first challenge outside the dome, planting evergreen giants that burst out of the ground.

In a fairy-tale finale, the teams create scenes inspired by "Jack and the Beanstalk," "Hansel and Gretel" and "Rapunzel," and one is crowned champion.
