BuBu ChaCha - Season 1 Episode 13 The Salmon Goes Upstream

Catherine decides to take Randy up the river to look at some Salmon. For the first time, Randy experiences the magnificent miracles of nature. He sees salmon making endless efforts to swim up the river to lay their eggs. ChaCha explains that some salmon cannot make it all the way and that was the way nature was. Randy feels sorry for the ones that cannot swim up, even though the weak ones are trying as hard as the strong ones. ChaCha is moved by Randy's thoughtfulness and decides to call Hippotruck to help them carry the weak salmon up the river.
