Thank you for viewing! This is a Plarail train set with an aquarium theme. One of the trains has a motion of a sea lion shaking its head and carrying a basketball. There is also a train that has an aquarium screen that rolls and changes when the train runs. The motions occur when the trains are run manually. They are not electric. The trains function well. As my child played with them at the time, please forgive any minor paint剥げ, deterioration of the train coupling parts (such as bending), and deterioration of the non-slip rubber attached to the wheels. Please check the photos as these are used items. We will ship anonymously. We do not have any pets, and we do not smoke. Immediate purchase and purchases made at night are welcome. Thank you for your consideration.
