Preschoolers can recreate their favorite railroad stories from Thomas & Friends: Big Adventures Together with these push-button die-cast toy train engines with amazing color-changing action! Children can collect their favorite characters from the series and watch the locomotives change color when placed in water. It will be like having two locomotives in one! Discover hidden decorations on each locomotive when you change the water temperature from warm to ice cold (and vice versa). Each train sold separately, subject to availability.
