droped one off a bridhe when we were kids once.....it swam across the current realy realy well and fast!
in a wood i once keeperd had a lot of mice,voles,shrews and moles...when the river burst its flood bank and the wood flooded..their was a carpet of dead rodents in one corner of the wood...but their wasnt a mole amoung them.. but i did see a mole swim across the flooded wood leaving a wake behind it.....
