Salmon are born in a river, after a while they swim out to the ocean, live there for a while, then return to the place where they were born to lay their eggs. The trip is called a salmon run, the trip's never easy there are bears, eagles, otters, sharks, and all sorts of other things. --#Instructions#-- Arrow keys to move up and down. Avoid boxes. Reach the nesting ground.
