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