Very adorable little train set. Includes Thomas and his 2 friends Percy & Kana. They are color changing which is a cute feature. The kiddos love taking them into the bath and watch the colors change slightly. They have a good weight to them and feel super sturdy. The wheels run smoothly and my kids love playing and racing them throughout the house individually as well as connecting them to each other and running them through varias obstacles. The color changing feature is subtle and shows the most on their faces. My kids show more interest in just playing with them during their bath time than being overly excited about the color changing feature. It's a neat feature for sure - my kids just seem to have lost interest quickly. Regardless of the kids losing interest in the color changing part of the toy - they really do like this toy and its functionality and it's a nice new addition to their collection. It's definitely a toy that is holding their interest and a toy that can withstand a lot of rough play. Highly recommend

My 4 year old loves water play snd trains. This is such a fun way to combine the 2. He was so confused when i handed these over and told him he could play with them in his water table. All of his other trains have batteries and definitely cant go in water. It was quite a fun surprise for him to get to put these in water and see the new designs pop up. Their faces all turn colors when placed in cold water. I did ice water for the colors, and hot to go back to normal. These are mini trains but fit on the normal tracks i have.
