Crash Bandicoot 2 Cortex Strikes Back Sinking Podium
Sinking podiums are podiums that appear in the river levels of Crash Bandicoot 2: Cortex Strikes Back and the Crash Bandicoot N. Sane Trilogy.

Some sink and rise up again in the river repeatedly, while some move up and down or side to side. Some even flow in one direction in a single file line continuously until they reach the end and sink.
