This is a fun set. The hammer makes a glass-shattering sound when squeezed. The screwdriver is a rattle, the wrench squeaks when squeezed and my set also came with a saw that crinkles. My son hasn't yet figured out where to squeeze the hammer to make the noise, but it's cute watching him try and surprising him with help. It's a great soft toy, and the fabric toolbox with velcro helps keep them together.
