Changes, Changes begins with two wooden people building themselves a home with blocks. When one of the blocks catches on fire, the people use the blocks from the house to make a fire truck. Water sprays from the wooden hose of the truck to put out the fire. Unfortunately, the water does not stop the flowing from the hose, creating an ocean. In order to solve the problem, the wooden people take the fire truck apart and use the blocks to build a boat.
The people sail the ocean on the boat until they reach land. Once there, they reconstruct the blocks that formed the boat to build a truck that will take them traveling. Next, they lay tracks and build a train from the blocks. Finally, the people end up where they started-- they construct a home again from the blocks used to make the train.
This is a wonderful story which holds the promise that any problem can be solved with a little creative thinking!
