Last night, we celebrated a major milestone inside the first Mattel Wonder Indoor Waterpark: the building exterior and signature retractable roof are complete.
Getting here has taken years of vision, planning and thousands of hours of work from a remarkable group of partners. Standing inside the building with them, hard hats on, made it clear how far this project has come.
Thank you to Mayor Rusty Hike and the for your leadership and belief in this project from day one. Thank you to Natalia Premovic and the Mattel , Inc. team for trusting us to help bring Barbie, Hot Wheels, Fisher-Price and UNO to life in a whole new way. And thank you to Martin Aquatic and every design and construction partner turning these renderings into a place where families will play.
The new interior renderings are out today, and they are only a preview of what's coming. We can't wait to welcome families to Bellevue, Nebraska, at the end of 2027.
