"Fisher" is a six-year-old, male, black bear, weighing close to 500 pounds, who was
relocated to the Folsom Zoo. Fisher is an expert at breaking and entering, which is
why he is used by Yosemite National Park, and others, to test bear-resistant devices.

Although Fisher had as much time as he wanted with the TKO, this video shows
his entire effort. The only edits are to eliminate a few seconds of unusable footage.
