This is a glitch in Crash Twinsanity that provides the player an easier or harder way to retrieve gems, most of which are for N. Sanity Island. For the gem, where the player must run the chickens into nitro crates, Crash can hop on a fence, and onto a tree, and then hop onto the platform where the gem is located. The clear gem in Twinsanity Island can be obtained easily by belly flopping over the force field. For some reason it's the only one that works. The red and green gems can be easily obtained through suicide (red) or a careful jump (green).
