Under water.....

I know.....very carefully!

I would think that walruses would be slower on land than in the water.

They repeatedly beat them on the head with a baseball bat.

Oh wait, that's man hunting seals.

They probably pick out a young, sick, or weak walrus that won't put up as much of a defense.

Vewy, vewy quietly on tiptoe.

Through a hole in the ice.

In camo vests...

by looking through their goggles...

I would guess on icebergs.

The bears talk about good food that is to be served and the walruses just show up uninvited. The end!

In tusk-any?

They go hunt them at Wal-mart.

They lure them with Canadian Club and Coke.

I don't think they do, as a rule. Unless they come upon a very weakened one. Or are extremely hungry. And I think it would have to be on land. A walrus would probably have the advantage under water.

This is so weird, I just got this story on my newsfeed from CBC.
