A little Fib turns into a big problem for Junior Asparagus! With dad's favorite bowling plate in pieces, Junior is sure to be punished until a strange visitor advises him to cover his tracks with a little white lie. Dad buys the story, but Junior notices his new friend seems a little bigger now, and a lot less cute!

Lies have a way of growing - and it isn't too long before Junior's "little fib" has grown into a 30 foot tall monster, threatening to devour all of Bumblyburg! Only one person to call in a crisis like this ... Bumblyburg's own super-hero, Larry-Boy!! But can anyone stop ... the Fib from Outer Space?!?
