Mystery Toy Trains Collection, Color Reveal Engines with Color-Changing Action & Cargo for Kids Ages 3+ Years, Each Sold Separately

It was perfect for my son 4 years

I got these as a reward for my kid and he thought he was getting a gift because they were “wrapped” in bags, They are great quality and are great for kids. My son has fun playing with them but says that the Percy engine isn’t the right color (he’s blue instead of green). When the package arrived I liked how everything was packaged. The only thing I would say is that it was a little harder to open. Great product!

This was by far my train obsessed toddlers favorite gift on Christmas. Once he opened it, he was no longer interested in anything else. I do however feel like it is pricey.

Got this in the mail as something to try for my little one who is a big Thomas the train fan. It was fun to watch his reaction when dipping the red coated engine into hot water where the coating came off (water turns a pale, pretty red) and reveals a blue colored Thomas the train. It will not change back and forth once the coating is removed the first time. My child does love the other accessories that so come with it (ours was a crab 🦀 and treasure chest on 2 separate train cars packaged in mystery plastic bags with question marks on them). Very cute little Thomas addition to add. Wish the train would continue switching back and forth colors in hot or cold water otherwise a nice product

Fun little gift for my 4 year old. Make sure you put a towel or a garbage bag or something on the floor before you dip the engine in the water. 😉

Very strange product, messy, never again

My 4 year old loved this! Only complaint is that it takes a while to get it to change color in cold water
