In this page you can find a detailed description for unlocking a golden trophy called "Cortex's Terrifying Trial" in Crash Bandicoot on PlayStation 4. You get this trophy by finding a key in Jaws of Darkness level.
Jaws of Darkness is one of levels available in Cortex Island (the picture above). In order to get this trophy you need to find all 3 Neo Cortex tokens, use a portal that takes you to a bonus round connected with those tokens and complete it by destroying all chests.
The first token is in one of the chests presented in the picture above. They are located next to the checkpoint.
The second token can be found shortly after reaching the location with spears sticking out which is presented in the picture above. Notice the hole marked in the picture. A snake jumps out of it BUT don't kill him with the Spin attack. Instead, you must eliminate the snake by jumping on him. It is very important because otherwise a pushed back snake can prematurely detonate a TNT chest that stands on a nearby ledge. Get there and destroy the regular chests first, inside one of them you can find the second Cortex token.
The last, third, token can be found shortly after reaching the pole presented in the picture above. The apples suspended in the air on the left rightly suggest that there is a hidden path there. Make a few steps to the left and a first platform will appear. Jump to the next apples but be quick because they will start to fall, one after another. You reach a secret location with chests and inside one of them you can find the third Cortex token.
Right next to you there is a portal that takes you to Cortex's bonus round. This secret level is rather difficult because most of the jumps must be done above a chasm. When you land on a TNT chest you must, at the last minute, jump on another. Repeat this move. Lastly, you must jump on six chests that are close to each other. The trophy is unlocked when you complete this stage and you can see its summary. As for the key it unlocks a Fumbling in the Dark bonus stage but you don't have to complete it to get this trophy.
