To catch a polar bear is a very simple process that requires just two items, an ice saw along with a can of green peas. Finding a spot on a solid piece of ice, cut a circular hole in it a little bigger than the size of the polar bear you want to catch.
Find a hiding spot and be patient. The green peas will eventually attract a polar bear.
When it arrives and starts to eat the peas, quickly but quietly run up from behind and kick it in the ice hole.
