Upstream

thumb|500px|right'Crash Bandicoot can't swim, but you need to up the stream if you want to beat Papu Papu.' -Level description

Upstream is the fifth level in the original Crash Bandicoot. As the name implies, you run across leaves on a river coming out of the first island. Watch out for the lily pads, as they sink shortly after Crash steps on them. The rest can be accessed by the Orange gem, which contains a more challenging portion of the level. At the end of this level is Papu Papu's home.
