Character: Trouble

Trouble is weird cat (is there any other kind?) who adopted the gremlins without their permission.  Trouble was found among the garbage cans by Lucas.  Lucas tried to rid himself of the cat before he returned home but the cat had other ideas.  Despite the gremlins’ efforts, they could not convince Trouble to leave.  They eventually gave up and tried to gaslight Elmo into believing that he had always had a cat.  Elmo was not deceived, and was going to throw the cat out but at the last-minute had a change of heart.
