While playing through the platformer Crash Bandicoot 4: It's About Time, you can find hidden regular stones and a few multi-colored ones. We tell you where to find the yellow diamond.
Look for the yellow gem on the Mosquito Marsh map, in Run It Bayou. At the very beginning of the level, instead of going into a small "boat", you need to slide jump onto the floating boxes in the far right (to the right of the boat). From the boxes you can jump onto the moving platform. To the left of it there are 4 drawers.
Jump on four boxes, hold the jump button (to jump higher) and double jump in the air. At the very top, outside the screen (screenshot below) is a yellow stone. It's really well hidden. You won't even see it because it's off screen.
Having taken the item, be sure to complete the passage of the level, hto receive a stone was counted.
