Tonight on "Dancing with the Stars" (Season 34, Week 4), Robert Irwin and his professional partner Witney Carson will hit the dance floor with a Cha-Cha to "Try Everything" from "Zootopia," embracing the show’s Disney Night theme. The stakes feel higher than ever for Irwin, who has charmed fans and judges alike in recent weeks. But as he takes on what’s being billed as his “most challenging yet” routine, he also carries a deeper mission: to honor the legacy of his late father, Steve Irwin. The couple has impressed fans with their previous performances and aim to impress again tonight.
