Ghost in the Machine

The kids test a falconfly repellent. All compounds are unsuccessful, except for a mystery mixture found by C.G. Also, things are being lost and the Time Flyer is moving on its own. What's more, the crew are seeing ghostly copies of themselves! Later it is found that Squibbon has learned to control the Time Flyer and chameliographic helmet and mixed the successful falconfly repellent! He also finds an egg in an unknown era that begins to hatch!
