Zerby Derby

On a rainy day in Zerby Town Zack and Lily find a stream washing the roads away. When they get to the top of the hill and find where the stream is coming from, Zack, Lily and the Construction Zerbies try to stop it with a dam. But when it overflows the Zerbies have to put their hoods together to come up with another solution, fast!

Zack and Rex are playing hide and seek but Rex is too big to hide! He tries hiding behind a rock, but he’s too big. Then he tries hiding in leaves, but the leaves blow away. He tries hiding in sticks, but there aren’t enough of them to cover him. But Rex is determined to try, try again until Zack can’t find him.

Axle and Zack come upon a giant bowl the Construction Zerbies have dug in the sand. When Axle drives into it and jumps out, all the Zerbies want to give it a try. But they all end up stuck at the bottom. They realize they need to get going very fast to get out so they put their hoods together and try, try again until they find a way to get out.

Zack and Rex are playing in the Zerby Town sand pit when they discover a big log. They call Strut the crane to help them build a ramp out of sand so they can get on top of it. But the sand just falls apart. So Zack and Rex look for answers to make the perfect ramp up to the log. Chase the helicopter is always watching over the Zerbies, but he's having a very busy day trying to keep track of everyone. Zack offers to help Chase with his duties, but it turns out, seeing from high up like Chase can is something Zack just isn't able to do.

Zack and Rex really want to play in the Zerby Town sand pit. But the pit is so small they can't both fit on it at the same time. They decide to travel waaay down the forest trails to the natural sand pit and haul back some more sand to make it bigger. But after Rex dumps the first load, they realize it will take forever.

Zack and Rex set out to solve the Zerby Town maze - something no other Zerby has ever done. But after driving to the center of the maze (which is the easy part) they get lost trying to get back out and have to call Chase the helicopter to come help them. But the friends decide to try, try again and set out to solve the maze on their own without the help of Chase. / Zack and Lily discover that Bob the boat doesn't have a garage.

Rex has built a ditch that goes right through Zerby Town. Zack thinks it's great, but Zerbies might need a way to cross over the ditch so they don't keep falling in.

The Construction Zerbies have made a fun table-top obstacle out of a large pile of dirt. But Rex really thinks it could use something else. Zack and Rex set out to build a tunnel through the side, with the help of the other Construction Zerbies.
