When placed on any object that’s red - he will react as if he’s touching fire🔥 . Blue garners water reactions & green ~ grass. Regardless if you buy more for the set, he will interact on his own to “collect coins” etc. You can expand, rebuild, role-play stories and create unlimited levels with other LEGO® Super MarioTM sets (sold separately).
