This page provides a detailed description of how to unlock "Penta's Revenge" Bronze trophy in Crash Bandicoot 3: Warped for PlayStation 4. You receive this trophy for defeating the second boss in the game - Dingodile'a.
During the battle, Dingodile will use a flamethrower and he starts with bombarding the area. At this point, start running in the counterclockwise direction and don't stop, or you will take damage from falling bombs.
After the bombardment stops, Dingodile will start using his weapon for smashing the crystals around him. Then, try to run left and right, in turns, and to avoid spots where he attacks (flames travel though crystals).
You can use to your advantage the fact that Dingodile smashes the crystals . Sooner or later, you will be able to dash between them and reach the boss (screenshot 1). Spin-attack him. Similarly to attacking TNT crates, this starts a countdown, so leave the central area quickly and await the explosion (screenshot 2). Dingodile will then lose a point of his health.
The rest of the battle is similar and the only difference lies in bombardments. In the second phase of the battle, avoid the attacks by mowing in the clockwise direction. In the last phase of the battle, move in the counterclockwise direction again, to avoid double bombardment. Just like earlier, keep an eye out for opportunities to deal damage to the boss, by Spin-attacking him. Depriving Dingodile three points of energy ends the battle.
