The slip-up started when two cubs fell over the edge of the waterfall. Their poor mother was standing on the sidelines, terrified.
She was so worried that her jaw literally dropped -- a dropped jaw is a clear sign of anxiety in bears.
This mama can't be blamed, though. She rushed to her cubs, likely fearing the worst.

A manatee calf nurses from its mother inside of the Three Sisters Springs in Crystal River, Florida January 15, 2015. On winter days, Florida manatees flock by the hundreds to the balmy waters of Three Sisters Springs, drawing crowds of snorkelers and kayakers to the U.S. sanctuary, where people may swim with the endangered species. But as tolerant as the gentle, whiskered sea giants can be of the accidental kicks and splashes of delighted tourists, wild life regulators want to ban most canoes and paddle boards and create people-free zones to protect the wintering "sea cow." Proposed limitations for this winter are awaiting approval by the U.S. Fish and Wildlife Service. Picture taken January 15, 2015. REUTERS/Scott Audette
