Every corner of the 33889 crane & mountain tunnel offers something new to discover. Crane and mountain top can be lifted off and placed on track separately for dual functionalities. In addition to the dual level railway passage and a majestic crane on top, four different sounds activate when the train is passing through the mountain. This crane and mountain tunnel is a treasure trove of playful function and design - you might even find some gold! Suitable for ages 3 years and up.
