Today it's all about triplets! Three grizzly bear cubs are expected to make their official public debut at ZooMontana in Billings today.

The siblings, named Dolly, Lou Lou and Koda, were brought to the zoo after their mother was euthanized for mauling three campers near Yellowstone National Park last summer. A Michigan man was killed and two people were hospitalized after the 216-pound grizzly tore into their tents in a nighttime attack at the Soda Butte Campground near Cooke City on July 28.

Krystal Whetham, ZooMontana's senior keeper, says the cubs were underweight and feared humans when they arrived, but they have since gained about 100 pounds each.

The 2-year-old cubs will make their public debut between 11 a.m. and 1 p.m. today.
