Fluffy had a big pile of blocks. He wanted to build a tall tower! But wait, where was the blue block? Fluffy grabbed his shiny magnifying glass to find it.
Fluffy crawled on the soft rug. Stomp, stomp, stomp! Look, look, look! Through the glass, a tiny crumb looked like a big hill. Fluffy giggled and kept searching for his block.
Fluffy looked at a fuzzy dust bunny. Look, look, look! It looked like a little cloud! Suddenly, he heard a sound. Squeak, squeak! The sound came from behind the big sofa.
Fluffy wiggled his peach-pink body to the sofa. He held his glass up high. Look, look, look! Behind a cushion, he saw two tiny ears and a long, pink tail.
It was Pip the mouse! Pip was napping next to the missing blue block. Squeak! Pip smiled and pushed the block to Fluffy. Fluffy gave his little friend a happy wave.
Fluffy put the blue block right on top. Yay! The tower was finished. Fluffy hugged his glass and felt like a very smart detective. What a fun, busy day for Fluffy!
