S02:É07 - S02:E07 - A Bridge for All Zerbies - Chase on the Water - in a Pinch

Zack and Axle find a bridge make out of sticks that crosses a small gap. The bridge, held up by two long sticks, can support Axle’s weight, but when Zack tries to cross, it breaks. They call Mika the mechanic to help them make a new bridge. They build one with 3 sticks which holds up Zack just fine, but when Mika tries to cross, it breaks under her heavier weight. Finally they build a bridge with 4 sticks that can hold up even Mika. But when Sandy the Bulldozer comes along, they realize they are going to have to build one more. - Chase is out exploring Zerby Town Forest when he comes across Bob the Boat and Piper the Float Plane watching a Lily pad, waiting to see a frog. Chase wants to wait with them but there’s nowhere for him to land. He tries landing on the water, but he’s doesn’t float. He tries landing on the shore, but he’s too far away. Then he tries landing on Bob, but Bob is too tippy for Chase to land on. Chase realizes he needs something light enough to fly with but something that will allow him to float. Once he finds some perfect sticks he can float as well as Flynn. - Zack, Lily and Rex are racing back to Zerby Town when Rex gets stuck under a fallen tree. Zack and Lily try to push him out but he’s truly stuck. Zack tries to pull while Lily pushes, but still no luck. They think that digging down would work, until they realize Rex is on rock, not dirt. Finally they realize that if Rex takes some air out of his tires, he will lower down enough to get out from under the log.
