Poor Olie. He's is too Rolie big to do this, too Rolie small to do that. But a turn with the shrink-and-grow-a-lator should fix all that...until Olie grows too much in this classic picture book-turned-beloved-TV-show from the brilliant mind that brought you The Fantastic Flying Books of Mr. Morris Lessmore.
Rolie Polie Olie grows a little every day, but his parents say he's still not big enough for a trip to Mount Big Ball. At the same time Pappy says Olie is too big to jump on his bed! Olie feels like he isn't the right size for anything. Then he gets a big and really bad idea: He'll use the shrink-and-grow-a-lator. But he presses the wrong button, and now he's a small as his sister Zowie's dollies! Olie finds the "bigger" button lickety-split and up, up, UP he grows...

But being grown up isn't all it's cracked up to be either. Olie bonks his head on the moon, burns his bottom on the sun, and lands with a big KABOOM on Mount Big Ball. Lost and lonely and so, so tall, Olie wishes he could be back to being just plain Olie!
