Once upon a time, there was a little girl named Amy. She loved to play with her colorful blocks. One day, she wanted to make a tall stack with her blocks. So, she started to try.
Amy put one block on top of another, but the stack was not very tall yet. She saw her cat, Mittens, who was very flexible. Mittens could bend and twist in funny ways. Amy said, "Mittens, can you help me make my stack taller?"
Mittens meowed and came over to help. With Mittens' flexible paws, they tried together to stack the blocks higher and higher. Finally, they made a very tall stack! Amy and Mittens were so happy. They had fun trying new things and playing together.
