Zerby Derby
Double Decker Zerby
While moving their garages around, Zack can't find anywhere to put his garage near Axle's. They decide Zack's garage should go on top of Axle's. This creates problems when they realize finding a solution for getting in and out of the second story garage isn't going to be easy. Zack falls out of his garage as soon as Strut puts it down. Then he can't get back up. They call Fill the Front-Loader to build a ramp up to Zack's garage. The ramp works perfectly, except it goes in front of Axle's garage door and Axle can't get out. They remove the ramp and try, try again. Axle realizes that if they turn Zack's garage sideways then Zack can have a ramp up the side of Axle's garage, and Axle can still get in and out.
