Ghost

Ghosts appear in the levels of Desert Island. They devour everything in their path, including Crystals and keys.

Description
They are slightly transparent, white, can float over huge precipices, and howl. They also have arms. They move much faster than Croc.

The challenge of these levels is to race these ghosts as these ghosts will destroy any crystal or more importantly silver keys that it runs into.

Most of the time you race the ghost in the dark, so it helps to know where the shortcuts are. When a ghost reaches the end of the level, it disappears.
