The Rock Crusher is a destination based off of the special, Blue Mountain Mystery. It was released in 2014 as part of the Merrick and the Rock Crusher Set. It includes a red Cargo Car and a clear cargo piece with rocks inside. When the button on top of the crusher is pushed, the rocks bounce around in the cargo piece.
- It was originally planned to be introduced in 2012, under the name Smashing Steam Hammer. However, it was delayed due to Fisher-Price's acquisition of the Thomas Wooden Railway license.
