A Toad house will also appear next to the beginning of the world map; the kind of Toad house that appears is determined by the last two digits of the timer. You can restore this house as often as you like. * 11, 22, or 33 restores a red Toad house (items). * 44, 55, or 66 restores a green Toad house (extra lives). * 77, 88, or 99 restores an orange Toad house (Mega Mushroom). =>Special Toad Shop: Once you beat the game for the first time, a special blue Toad shop will appear at the beginning of the world 1 map.
