The Fib is an alien from an unknown galaxy. He has the power to grow and shrink to lies and truths. His only appearance was in Larry-Boy and the Fib from Outer Space where he is the main antagonist. His goal was to make Junior Asparagus tell enough lies so he can grow to at least thirty feet tall and wreak the city of Bumblyburg. He was about to succeed and eat Junior and Larry-Boy but Junior comes through and tell the truth about Dad Asparagus's Art Bigotti bowling plate, causing the fib to shrink to nothingness. Another fib landed in Bumblyburg later, however, this one was red instead of blue.
