"Urrr...!" - Lab Gremlin The Lab Gremlins were two of the many gremlins that invaded the Clamp Center building. They spawned from either George, Lenny or Daffy and made their way into the Splice O' Life lab in the building. There, they took lab coats and wore gloves and mimicked Martin and Lewis, two of the scientists there. They also witnessed the transformation of both the Brain Gremlin and Bat Gremlin.
