For all of their silly and playful antics, bears can be incredibly serious when it comes to eating — and incredibly weird about what they consider food.

Strawberry-rhubarb pie? Nah. Beans? No thanks. A plastic kayak, though ... that did nicely for one bear's lunch in Alaska this week.

YouTube user Mary Maley uploaded a video to her account on Tuesday that purports to show what happened during a recent bear encounter she had in Southeast Alaska.

According to the video's caption, Maley was on a 172-kilometre solo kayak trip in Alaska that was intended to go from Ketchikan to Petersburg. Her journey was cut short, however, after she stopped to rest outside a U.S. Forest Service cabin in Berg Bay.

"I had just carried my tent, food, and all my gear into the cabin to dry while I went on a 4 mile hike that begins just behind the cabin," she writes. "I heard something outside as I ate my lunch, and well, I never got to go on that hike."

Maley says she started filming the black bear outside her temporary shelter about five minutes after it arrived. 

"Thank you for leaving my kayak alone!" she shouts to the bear at the beginning of the video as it explores the site.

Then she gets a lot less friendly with the animal.

"I'm going to pepper spray you in the face, that's what I'm gonna do to you," she threatens before actually shooting pepper spray towards the bear. "Go away!"

As Maley continued yelling, it slowly walked over to her kayak and started chewing.

"Stop it, bear! Stop it. Bear. Bear. Bear... You're breaking my kayak! Why are you doing that? Why are you breaking my kayak?" she shouts. "Bear! Please stop breaking my things! It's not — it's not even food. It doesn't even taste good! It's just plastic!"

Maley explains in the caption of her video that the bear continued to gnaw at the kayak for another five to 10 minutes after she stopped filming.

After retrieving the chewed up vessel, Maley says she swam to a boat anchored in the bay nearby. She then managed to hitch a ride to Wrangell, Alaska, where as of Tuesday she was still trying to repair her only means of transportation.

The Alaska Dispatch, which has been unable to contact the kayaker, notes that this isn't the first case of bear-on-vehicle violence to have been reported in the area.

"Back in 2009," the newspaper writes, "a bear tore into a plane parked in Southwest Alaska."
