## Description

Preschool kids can unbox hours of exciting railway play with these Thomas & Friends Color Reveal & Surprise toy trains from Fisher-Price. Kids can unbox and dunk the mystery engine in warm water to reveal who it is! Then discover hidden decorations on the engine by changing the water temperature from warm to icy cold (and back again). Each engine also includes 2 cargo cars and 2 surprise cargo pieces for kids to unwrap, load up, and send racing around with the engine. Compatible with any Thomas & Friends track (Track sets sold separately & subject to availability.) Colors and decorations may vary.

Review: Perfect for Kids - 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!
Review: Good project - It was perfect for my son 4 years

### ⭐⭐⭐⭐⭐ Surprise Train
*by A***R on January 6, 2025*

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.
