Puddle Too Deep

While exploring Zerby Town Forest, Zack and Rex come across a puddle. But they can't explore the other side of the puddle because it gets too deep for Zack. They try to come up with solutions to make the puddle shallower so Zack can cross to the other side. They try using a large piece of bark, but when Zack gets on top of it, the bark starts to float Zack around. Rex tries to add more dirt to the bottom of the puddle, but the dirt just ends up mixing with the water and going away. Finally they decide to use gravel, which doesn't mix with the water and stays put on the bottom of the puddle. Zack gets across and he and Rex decide to fix all the other deep puddles too!
