For most of the year, Tempe Diablo Stadium is a quiet, sun-bleached ballpark on West Alameda Drive, the kind of place that smells like cut grass and Cactus League optimism in March and then sits mostly empty once the Angels pack up for the summer. Starting Sept. 30, it becomes something else entirely after sundown: a glowing zoo where the animals have clawed their way out of the grave and started to dance.
Zombie Zoo is the newest production from World of Illumination, the Tempe-based company that has spent years turning parking lots and stadium grounds into drive-through worlds of synchronized light. The show runs nightly through Nov. 1, and it is the company's first Halloween attraction at the Tempe ballpark, which has hosted its Christmas show, Reindeer Road, in recent winters.
The premise, as the company tells it, is a zoo that borders a graveyard. On Halloween night, when the clock strikes twelve, the mascot, a gorilla named Tumba, beats his chest and stomps the ground hard enough to wake every last animal from its grave. One by one they climb out, shake off the dirt, and fall into formation, because when Tumba choreographs, everybody dances. Drivers pass desert mummies and savannah zombies, bamboo groves lit by spirit lanterns, and a DJ Monkey spinning a Halloween soundtrack. There is a swirling jack-o'-lantern vortex tunnel and a dancing graveyard, and the whole thing is scored to music piped into the car, so nobody has to leave their seat.
That last detail is the point. World of Illumination built its reputation on the idea that a holiday outing does not require standing in line in the cold. Guests stay in their vehicles, tune the radio, and roll through at their own pace. One general-admission ticket covers an entire car, which is why the pricing is quoted per vehicle rather than per head. Tickets for the Tempe run start at $39.99 per car. The company sells tickets online only and keeps the show open rain or shine.
To understand why a Halloween zoo exists at all, it helps to know the man behind the lights. World of Illumination grew out of the ambitions of Simon Kreisberger, a native New Yorker who worked for Michael Bloomberg before moving to Arizona. He had attended Arizona State University in the 1990s and always meant to come back. In 2004 he opened an indoor play space called The Play Factory near an outlet mall, betting that Phoenix's brutal summer heat made indoor recreation a necessity rather than a luxury. It was, as he later put it, a home run from day one.
But the lights were the real dream. Kreisberger spent roughly a decade thinking about a drive-through holiday attraction before he finally built one, an experience he first called Illumination: Symphony of Light. The concept was deliberately more than strings of bulbs stapled to plywood. "Anybody can do that," he told Phoenix New Times. "We wanted people immersed in a Christmas environment." The result featured giant Frostys and colossal Santas flickering in time to music broadcast straight into visitors' car radios, and Kreisberger was confident enough in its scale to apply for a Guinness World Record listing as the world's largest animated holiday show.
That show became World of Illumination, and the company expanded well beyond the Valley. By October 2020 it was breaking ground on a Candy Rush theme park at Six Flags White Water in Marietta, Georgia, complete with a 40-foot trio of candy canes installed by crane and billed as the largest candy-cane structure in the world. The timing was fortuitous: a drive-through attraction was, almost by accident, perfectly suited to a pandemic year. "All of us at World of Illumination have been working hard for many months to provide safe and much-needed family entertainment to the community," Kreisberger said at the time. The company now describes itself as having welcomed more than six million guests, with shows in Arizona, Georgia, Florida, Illinois, Tennessee, and Nevada.
The Halloween expansion is a newer chapter. Zombie Zoo first took shape in the West Valley, at the company's Glendale location, where World of Illumination pitched it as a gentler alternative to the haunted houses and jump-scare mazes that dominate October. The company's own description of the Glendale show leans into that distinction: not every Halloween attraction needs dark hallways and things leaping out at you. A zoo overrun by zombies, in this telling, is playful rather than terrifying, a world where younger visitors can be thrilled without being overwhelmed. The theme also fits Arizona's particular calendar. By the time October arrives, the brutal summer has broken, neighborhoods start decorating, and families are looking for reasons to be outside again.
Bringing the concept to Tempe means bringing it to a ballpark with its own long history. Tempe Diablo Stadium opened in 1968 and has served as the inaugural spring training home of three different franchises: the Seattle Pilots in 1969, the Milwaukee Brewers in 1970, and the Seattle Mariners in 1977. It has been the Los Angeles Angels' spring base for years, and the city and the team reached a deal to keep the Angels there through at least 2035, with an extensive renovation planned. In the off-season, though, the stadium's vast parking areas and open grounds make it an unusually good canvas for a drive-through production, which is exactly how it ended up hosting Reindeer Road each winter.
World of Illumination makes a point of never repeating itself. Each season brings an entirely new theme, story, and set of displays, a promise the company repeats on its ticketing pages: no two seasons are ever the same. That approach is part of why a Halloween show can exist alongside a Christmas one without feeling like a rehash. Reindeer Road is scheduled to return to Tempe Diablo Stadium from Nov. 13 through Jan. 3, 2027, meaning the ballpark will flip from graveyard to winter wonderland in the space of about two weeks.
For now, though, the focus is on Tumba and his restless menagerie. The show is designed to be experienced from inside a car, with the windows up or down as the driver prefers, the music coming through the speakers, and the lights moving past at a walking pace. It is, in the company's framing, a party under the moonlight, one that ends when the moon begins to fade and Tumba takes his bow, sending the animals shuffling back into the dark until next Halloween.
Zombie Zoo runs Sept. 30 through Nov. 1 at Tempe Diablo Stadium, 2200 W. Alameda Drive. The show operates rain or shine, with tickets sold online in advance and priced per vehicle.
