Mind eel

Mind eels were creatures that thrived when sollar flares hit a planet's surface. The flares excited them and weather forecasts recommended the watching of mind eels and their offspring during this time. These creatures did not threaten nearby farmers, as they complied with the crop boundaries set in The Relevant Farm Acts of Thairwsthis 12.

Behind the scenes
Mind eels were mentioned in a one-page weather forecast titled "Region 29: The West Fissure," written by Bob Carrau for the 1993 book Monsters and Aliens from George Lucas, a publication that collects concept designs and photographs from various George Lucas projects. Lucasfilm employee Leland Chee, who maintains the Holocron continuity database, has indicated that information contained in the book is non-canonical.
