One day, a smart dog named Max found a big stack of blocks. The blocks were many colors like red, blue, and green. Max wanted to play with the blocks and build something fun.
Max started to build a tall tower with the blocks. He put one block on top of another. But then, the tower began to wobble and shake. Max knew he needed to reverse what he was doing.
Max took the blocks off the tower one by one, reversing his work. He then built a new tower, making sure it was strong and safe. With the tower complete, Max was happy and proud of his smart work.
