Speaking on a live Q&A with Animal Planet, Robert, 14, spilled the beans admitting his sister stashes toilet paper in her suitcase - Charmin to be exact.
“Do you have to tell the world that?” Bindi laughed.
“Your toilet paper is really soft here but I think we could have not said that on live Animal Planet Facebook feed but that’s cool.”
Terri then cut in saying that people actually send toilet paper to her for Bindi.
“She’ll ask for it,” Terri said.
“My aunt texted me from Oregon and she said ‘what would you like for your birthday?’ and, I love cards because I love writing to people, so I asked her for cards and toilet paper,” Bindi added, trying to hold back tears of laughter.
