- Clear Gem - Destroy 24 chests.
During this whole level you are riding a hog and can't stop. At first reaching the end might be very troublesome - many obstacles and hostile locals are placed in such positions that it might be hard to avoid them.
//film_do_dodania: Crash Bandicoot PS4 - How to complete the Hog Wild level?
Be ready to repeat this level at least a few times - memorizing the whole track will make it much easier to avoid all obstacles and destroy all chests. The main obstacles in this level are stakes with spikes, chasms (in order to jump over the one on the above picture you must bounce from the drum - hold the jump button) and natives that will be moving from the left to the right and back to the left.
As for the chests, destroying all of them might be troublesome as well because many of them are placed near each other. In such cases you must perform a perfect slalom and barely touch the chests - otherwise you won't be able to move the hog towards the next objects.
In the final phase of the ride you will encounter a new type of obstacles - grilled hogs. Jump over the first hog. As for the second one, simply run under it. The third one is shown on the above picture. In this case you must jump, but use it after a slight delay. This will enable you to avoid hitting an obstacle and to avoid having to repeat the level (after this trap all that's left is to avoid a single local).
