Jim and his team tried to dig around the beaver, but because it was half-submerged in the water, their efforts proved to be useless. They needed to devise a plan to somehow get underneath the animal and hoist it out. Then, Jim realized exactly what they needed: a pulley system. So they got a rope, and Jim managed to tie it around the creature’s torso. They had hoped that this would work, surely? Then the team quickly realized that there was one enormous flaw in their strategy.
