Crash Bandicoot/Upstream

Here it starts to get a little tougher. You have to go up the river jumping on logs, leaves and water lilies without falling into the water. Beware of carnivorous plants: the lighter ones will swallow you if you stay on top of them for too long, while the dark ones open and close at regular intervals. Watch out also for flying fish, which come out of the water. At the end you will find the exit portal.

To get the white gem in this level, you'll need to first get the orange gem from "Generator room". Only then can you reach the last boxes.
