A Genetically Engineered Adaptable Pet, or Geap, is a life form created by humans. They have a telepathic influence on humans to make them protect them. Wars were started over Geaps and many planets destroyed.
In The Geap, a Geap arrives on Red Dwarf in an escape pod. Lister looks after the Geap and instantly becomes protective of it. Cat steals the Geap for his dinner, causing Lister to grab a Bazookoid and go after him. Kryten manages to persuade Lister to hand over the Geap, and sends it away from Red Dwarf in the escape pod it came in.
