Zerby Derby

T02:C11 - S02:E11 - Axle’s Hill - Zerby Bridge - Sand Puddle

Zack comes upon Axle who is struggling to drive up a hill with a large flag that he made. Axle’s tires aren’t very good at gripping the dirt. Zack’s tires are very grippy but he doesn’t have enough power to climb the hill with Axle’s big flag. They call the strongest Zerby they know, Rex. But Rex can’t climb the hill either, because he’s a heavy truck and even all his power isn’t enough to make it up the hill. Sandy the bulldozer comes by and the Zerbies learn that not only are Bulldozers super powerful, but the caterpillar treads grip the dirt even better than wheels. Sandy not only carries the flag to the top of the hill, but tows up Axle, Zack and Rex as well. - Zack and Rex are exploring when they come across a small stream. They decide to try to cross the stream, and they think back to a floating log bridge they took to get across the lake. They make a floating log bridge but when Zack gets on the bridge the current of the water pushes the bridge down the stream. They try, try again, this time to make a bridge that won’t move. A bridge of dirt! But when Rex pours in a load of dirt – it just gets washed away. Rex and Zack know there’s a way to solve the problem, but they have to but their hoods together to figure it out. Rex realizes that if they make a log bridge that is above the water, then it won’t get washed away and they can cross. No sooner have they made the bridge than Rex is in the water with his life-jacket, trying it out from below as well. - Zack and Rex are having fun playing on Zerby Town Ridge. But the one thing that the ridge doesn’t have is a big mud puddle. Zack and Rex decide to make one. They get some dirt and they get some water and put them together in a hole. But no matter how much they mix them together, it just doesn’t make mud. They decided to add more dirt. No good. They call Walter the wash truck over to add even more water. Still no mud. They are confused. They go off looking for answers and find out from Fill the front loader that they were using sand, not dirt. They realize sand and dirt are very different. Dirt and water make mud, but sand and water make… sand castles!
