Preschool kids can recreate their favorite railway stories from the Thomas & Friends: All Engines Go! series with these diecast metal push-along toy train engines and other vehicles with awesome color-changing action! Kids can collect their favorite characters from the series and watch as the engines or vehicles change color when placed in water. It’s like having 2 toys in 1! Reveal hidden decorations on each by changing the water temperature from warm to icy cold (and back again). Each engine or vehicle sold separately and subject to availability. Suitable for ages 3 and up.
