Crash Bandicoot 4: It's About Time: Part 67: N. Verted Ship Happens (Perfect Gem Run)

The mirrored version of Cortex's section of this level threw me off a bit more than I would like to admit, namely in the Nitro area right before the character switch. The Hidden Gem is now located high above a tall stack of crates in the Crash/Coco section of this level. You reach this using the Arrow Crate at the top of the stack.
