The Red Fib is an alien fallen from space seen at the end of LarryBoy! And the Fib From Outer Space. No one knows about his whereabouts, but is assumed it went to Laura Carrot's house. So far this is his only appearance and has not had any lines.
This version of Fib looks exactly like the blue version only red.
