Spooks is the 64th level in Chip's Challenge 1. The infamous teeth trapped by dirt litter this level, which is actually a rather easy solve if they are never released. However, the route for 547 is one of the toughest melee routes in Chip's Challenge because of the sheer number of teeth (ninety-five of them!). If there wasn't a totally safe route, Spooks would be rated significantly higher.
The AVI solution shows the 547 route, which requires even step; near the very beginning and as the clock ticks from 563 to 562 are two [1] pauses. Otherwise, there are no tricks required other than a cool head and some math. But just think how tough it was to devise this route...
