This $28 million estate in Dallas's most exclusive neighborhood includes not one, but two mega-mansions. One is the living quarters, but the other is completely devoted to sports and entertainment.
The most jaw-dropping feature of all is the giant water park hidden out back… which is haunted.
CNBC got a full tour of the Texas-sized estate and the scary backyard water world for an upcoming episode of "Secret Lives of the Super Rich."
Take a look inside:
There's 37,000 square feet of space between the two French-style mansions.
The main house includes ornate features like a giant pink and white glass chandelier and marble columns throughout. There are also some features you're not meant to see, like a secret stairway hidden behind a bookcase that leads to the bedrooms on the mega-home's upper level.
The fun house, on the other hand, has a bowling alley, a gaming room and an indoor-basketball court. which does double-duty as a nightclub with programmable party-lights overhead and a professional DJ booth.
But the biggest splash on this property is in the backyard, where a colossal private water park delivers three giant water slides that spill into a 750,000-gallon pool. There's even a zip line overhead.
There's also a winding lazy river that flows into a massive water-filled grotto — where things get creepy. The water cave is overflowing with skeletons, mummies, bats and other creatures of the night! All of them come to life thanks to a high tech animatronic system and recordings of haunting screams that echo off rock walls.
The cost for the resort the owners built in the backyard is a whopping $10 million.
Watch a new episode of CNBC's "Secret Lives of the Super Rich," Thursday at 10P/ET.
