Bella & Dani Thorne: Polar Bear Pair

Bella and Dani Thorne step out at San Diego Zoo’s Launch of the Polar Bear Plunge late last week.

The duo joined pals Olivia Grace, Tori Spelling and Candace Cameron Bure, among others, at the launch.

The launch debuted the new renovated polar bear exhibit with a global warming message. Polar Bears Kalluk and sister Tatqiq, and Chinook now have their own new backyard space with displays showing how arctic ice is receding and a three-dimensional carbon graph charting skyrocketing global CO2 emissions.

Other features cater towards children and families — gigantic storybooks through which kids can flip, a polar bear den into which they can crawl, and an arctic research helicopter for photo ops.
