When you have collected enough gems in a stage a little icon of Spyro's head charging appears in the top right hand corner, meaning you can move through enemies for a short period. These enemies kill you if you touch them, unless you have charge mode on. There are 3 corridors, each with a Rhynoc (or possibly a Gnorc, it's quite hard to tell with such tiny graphics) that moves around. Like if it was released as an LCD game back when LCD games weren't so cheap they could be given away with fast food, some people probably would have bought it and enjoyed it. I thought I would leave the best til last, this one is actually really good.
