If you look for special sparkling points, you can find mini-games in four areas throughout the game. One is available if you open the flower near where you can usually find Rosetta (if you're having trouble, Idalia will teach you how to open flowers). A second game is available if you look for a sparkle on the water, near the Minister of Summer (it must be a full moon, though, or the sparkle won't appear). You can find a third game if you travel to the toadstool hatches and spin above the mushroom on the far right, another skill you can learn from Idalia. Finally, the rainbow butterfly will fly away and leave a sparkle behind, if you wake it during the winter. You can visit Nollie to learn how to wake insects.
