Bob the Builder has been given a computer-generated makeover by TV bosses.
The original episodes of Bob the Builder were created with models, like Shaun the Sheep.
But the new episodes will be computer-generated and Bob himself looks a little different.
The new Bob is taller and has a completely new face. He'll also have a new voice when the show returns in 2015.
HIT Entertainment that makes the show said although Bob looks different he will have the same "emotional warmth" as old Bob.
The series used to be shown on CBeebies but the new episodes will be shown on Channel 5.
