“Oh my God!” Irwin said as she saw the setup for the first time, as brother Robert and her husband laughed. “What is that?! That just gave me the biggest heart attack of my life!”

Robert joked to the cameras, “She can’t even articulate how much she loves it.”

Last month, Irwin shared anInstagram Reel, explaining that the couple took daughter Grace toAustralia Zoo’s Elephant Gift Shop to go on a stuffed animal shopping spree in celebration of her “unbirthday.”

“We have a family tradition of celebrating ‘unbirthdays’ when you turn a half ❤️,” she explained. “Happy two and a half unbirthday to our beautiful Grace Warrior.”

The video showed the sweet toddler naming the different animals as she perused the selection, holding as many as she could in her arms before passing some off to mom.

“So much happiness in one video. I love you both ❤️,” Powell, 26, commented.
