A Ghost is a unique type of Enemy in Croc: Legend of the Gobbos. There are six of them in total, one for each normal level on the Desert Island, and only this island (although it may be possible that the same single ghost appears in all six levels). A ghost is faced in every Crystal Door Challenge.
They are slightly transparent, white, can float over huge precipices, and howl. They also have arms and move slightly faster than Croc. They cannot touch or hurt Croc and vice versa (but are labelled as enemies due to attempting to stop Croc from getting the Key), and follow the same path every time the section is played. They have the ability to dispensary at the end of their path (where they key is located regardless of whether or not Croc has collected it).
