Zerby Derby
Fill-A-Vator
Zack and Lily are exploring Zerby Town forest when they come across a rock that's a little too high to get up on. With Strut the crane busy, Fill the front loader comes by to help. Fill can lift Zack and Lily in his scoop to the top of the rock, but when he tries he finds out that Zerbies are heavier than a scoopful of dirt, and he can't keep his balance. At first, Lily balances on the back of Fill to weigh him down so he can lift Zack. But when Zack gets to the top of the rock and its Lily's turn to ride in the scoop, there's no one to balance on the back of Fill. Before long the Zerbies realize they can use a rock on Fill's back to help him keep his balance while he lifts Lily.
