The Desert Ship(s) are a set of grounded ships that have been breifly seen by Honeydew and Xephos during their adventure. One of the ships was spotted during Isabel's story. Another ship was visited by Xephos and Honeydew when they were looking for a healer to help Professor Webley. The ship belonged to Shiplord Hubert, who abandoned it in order to help Honeydew and Xephos find the Oasis.
There are many possibilities and theories as to how the ships ended up in the desert, since Hubert never officially explained how he got there. The ships may have been from BBQ Bay and were cast into the desert by unknown means. All of the ships that have been spotted are said to look identical to each other. A third ship has said to have been spotted near the Desert Tower. The other ships may belong to other Shiplords and may have been part of a fleet.
