You survived Temple Ruins, no? So you can do Generator Room also - it the same type of level, except it's in Cortex Power. - Level description
Generator Room (はつでんしつ しんにゅう lit. Intruding into the Generator Room in Japanese) is the twentieth level (including boss fights) and is the third level of the third island in Crash Bandicoot and the Crash Bandicoot N. Sane Trilogy remaster of the first game. It contains the orange gem. It is similar in style to the ancient temple levels, Temple Ruins and Jaws of Darkness, but set in Cortex's power plant, and complete with robotic enemies.
The level also features a very large platform that drops permanently 10 seconds after Crash first touches it. It is the largest piece of interactive environment in all three games of the Crash Bandicoot trilogy.
Translation of Aku Aku Hints in the Japanese Version
There are monitors showing Cortex's face. Notice that you can jump and step on them. You'll have the good feeling that you're stomping on Cortex.
This level was the second successful level made for the game during its development. The first being Heavy Machinery.
Pinstripe Potoroo leaves a message on the final door in this stage, claiming to be the CEO of Cortex Power. It is never explained in-game. On the final door, Pinstripe's full name is spelled "Pinstripelli Potorotti".
At the start of the level and on some other parts of the level, Cortex's face is on what appears to be a TV screen. On these screens, there is no "N" on his forehead. It's a common mistake to think that touching a Cortex Screen will electrocute Crash. In fact, Crash only gets electrocuted if he steps on either an exposed wire segment of a Cortex Screen, however, only a few Cortex Screens have a long enough wire segment for Crash to step on; or a generator, however, this can only be done intentionally, and if the generators weren't there, Crash would simply fall to death.
In the prototype, the hologram probes appear as floating orbs instead, like in Heavy Machinery. They will still harm Crash if he touches them.
