WORLD'S LARGEST INTERACTIVE WATERPLAY
STRUCTURE TO BE FEATURED AT NEW
SIX FLAGS HURRICANE HARBOR WATER PARK
IN GURNEE, IL

Eight Water Slides and Nearly 500 Interactive Waterplay Elements Will Give
Families Hours of Exciting Fun

GURNEE, ILLINOIS --Pirate ships, water slides, adventures… oh my! Kids young and
old will love the good, clean, pirate-y fun of Six Flags Hurricane Harbor's star attraction
Skull Island, the largest interactive waterplay structure in the world with close to 100,000
square feet of climbing, sliding, splashing, soaking fun for kids and adults, alike. This
multi-story interactive waterplay area, will feature nearly 500 water gadgets, eight water
slides, an "erupting" volcano and three enormous buckets that periodically drench
guests with thousands of gallons of water.

"The family play area at Six Flags Hurricane Harbor is destined to be the most popular
place in the water park," says Tim Black, vice president and general manager of Six
Flags Great America and Six Flags Hurricane Harbor. "This part of the water park will
be larger than life, with a myriad of exciting activities for both kids and adults."

The interactive waterplay structure, which will anchor the new Six Flags Hurricane
Harbor water park slated to open in Spring 2005, will feature a Caribbean island theme
with Spanish-style bell towers, pirate references, treasure chests, water cannons and
hundreds of activities.

The entrance to this dazzling maze of twisting slides, shipwrecks, and thatch-roofed
canopies is Skull Tower, a 66-foot walk-up structure from which two serpentine slides
originate. Dubbed Skull Tower because of the six-foot skull that greets visitors from atop

the structure, the tower will be topped with an eight-foot bucket that douses guests
every 10 minutes with more than 1,100 gallons of water.

The play structure features 17 play towers interconnected by transfer bridges, swinging
bridges and cargo net climbs, for a total of 2,700 square feet of elevated platforms and
walkways. Scores of fountains, sprayers, jets, pumps, water wheels and other
interactive water features will be located throughout the play structure.

An active 50-foot water volcano featuring a geyser-like eruption will cap another of the
complex's towers. Two water slides will originate from different levels of the Volcano
Tower and two additional 40-foot towers will be ready to let loose 750 gallons of water
each.

The waterplay structure will include eight unique water slides that will twine among the
towers' supports. The incredible variety of slides – from a 6-foot tunnel slide to a 42-foot
serpentine slide --will guarantee that every guest will find a slide they love.

"The sheer size of this colossal play structure will keep families exploring for hours, as
they discover the more than 500 interactive elements that make this play structure the
world's largest," Black concluded.

This massive waterplay area will be connected to an activities area geared toward
smaller guests, just steps away from Six Flags Hurricane Harbor's other towering water
slides, rivers, pools and other attractions.

This family attraction is being designed and manufactured by Koala Play Group, a
Colorado company that specializes in play structures. The company collaborated with
Proslide, of Ottawa, Ontario, to integrate water slides into the giant play structure.
